An opinionated collection of programming languages. This is a list of what I consider interesting. Requests to add to this list are welcome, but there is no guarantee I’ll include them. As you can see many mainstream programming languages are misssing from this list.
- Alore is a language that explores optional typing in a Python-like programming language.
- Alpaca is a statically typed, strict/eagerly evaluated, functional programming language for the Erlang virtual machine (BEAM). At present it relies on type inference but does provide a way to add type specifications to top-level function and value bindings. It was formerly known as ML-flavoured Erlang (MLFE).

Ballerina incorporates fundamental concepts of distributed system integration into the language and offers a type safe, concurrent environment to implement microservices with distributed transactions, reliable messaging, stream processing, and workflows.”
- Boomerang is a language for writing lenses—well-behaved bidirectional transformations—that operate on ad-hoc, textual data formats. Every lens program, when read from left to right, describes a function that maps an input to an output; when read from right to left, the very same program describes a “backwards” function that maps a modified output, together with the original input, back to a modified input.
- C2 an evolution of C, using LLVM.
- Cell offers, among other things, a very flexible, entirely structural type system; deterministic, repeatable execution; support for reactive programming; the ability to use relations to store data; transactions and propagation of undefined values for error handling; and ortogonal persistence. “Cell is designed to complement and integrate with your primary language, not to replace it. Once a component of an application has been implement in Cell, the compiler will generate from it an easy-to-use Java, C++ or C# class that can be integrated into an existing project. Support for other languages will be added in the future.”

Its concurrency model is inspired by Go-style processes and channels. Flix compiles to JVM bytecode and runs on the Java Virtual Machine. Flix supports full tail call elimination which means that tail calls (even to other functions) never overflow the stack.”
- Futhark - A High Performance Functional Array Language. “a small programming language designed to be compiled to efficient parallel code. It is a statically typed, data-parallel, and purely functional array language in the ML family, and comes with a heavily optimising ahead-of-time compiler that presently generates GPU code via OpenCL, although the language itself is hardware-agnostic.”

- Inko ” is a gradually-typed, safe, object-oriented programming language for writing concurrent programs. By using lightweight isolated processes, data race conditions can not occur. The syntax is easy to learn and remember, and thanks to its error handling model you will never have to worry about unexpected runtime errors.”
“Inko is an object-oriented programming language, drawing heavy inspiration from Smalltalk, Self, and Ruby. There are no statements used for conditionals and loops, instead Inko uses message passing for (almost) everything.” Processes don’t share their memory, and communicate by passing messages, which are deep copied. This removes the need for explicit synchronisation, and makes data race conditions impossible. Inko uses a high performance parallel garbage collector, based on Immix. Each process is garbage collected independently, removing the need for a global stop-the-world phase. Inko is an interpreted programming language, with a bytecode virtual machine written in Rust. Inko is gradually typed, with static typing being the default. This gives you the safety of a statically typed language, and the option to exchange this for the flexibility of a dynamically typed language. Related reading:

- Koka – is a function-oriented programming language that seperates pure values from side-effecting computations, where the effect of every function is automatically inferred. The language is strict (as in ML), but seperates pure values from side effecting computations (as in Haskell). Through the effect types, there is also a strong connection to its denotational semantics, where the effect type of each function has a direct translation to the type signature of the denotational function. more Recently, Koka fully supports user-defined effects through algebraic effect handlers.

Picat is a rule-based language, in which predicates, functions, and actors are defined with pattern-matching rules. Picat incorporates many declarative language features for better productivity of software development, including explicit non-determinism, explicit unification, functions, list comprehensions, constraints, and tabling. Picat also provides imperative language constructs, such as assignments and loops, for programming everyday things. The Picat implementation, which is based on a well-designed virtual machine and incorporates a memory manager that garbage-collects and expands the stacks and data areas when needed, is efficient and scalable. Picat can be used for not only symbolic computations, which is a traditional application domain of declarative languages, but also for scripting and modeling tasks.

- Scopes – The language is expression based, but primarily imperative. The syntactical style marries concepts from Scheme and Python, describing source code with S-expressions but delimiting blocks by indentation rather than braces. Closures are supported as a zero-cost abstraction. The type system is strongly statically typed but fully inferred, therefore every function is a template. Both nominal and structural typing are supported. Type primitives roughly match C level, but are aimed to be expandable without limitations. The memory model is compatible to C/C++ and utilizes simple unmanaged stack and heap memory. Scopes provides many metaprogramming facilities such as programmable macros, deterministic/guided folding of constant expressions, metadata necessary for basic step-by-step debugging as well as inspection of types, constants, intermediate code, optimized output and disassembly. The environment is suitable for development of domain specific languages to describe configuration files, user interfaces, state machines or processing graphs. Scopes embeds the clang compiler infrastructure and is therefore fully C compatible. C libraries can be imported and executed at compile- and runtime without overhead and without requiring special bindings. The SCIL (Scopes Compiler Intermediate Language) is suitable for painless translation to SSA forms such as LLVM IR and SPIR-V, of which both are supported. The SPIR-V compiler can also emit GLSL shader code on the fly. The Scopes compiler fundamentally differs from C++ and other traditional AOT (ahead of time) compilers, in that the compiler is designed to remain on-line at runtime so that functions can be recompiled when the need arises, and generated machine code can adapt to the instruction set present on the target machine. This also diminishes the need for a build system. Still, Scopes is not a JIT compiler. Compilation is always explicitly initiated by the user.

Comby is a tool for matching and rewriting code. You start by writing a simple template to match syntax. Look at this Go function:
