When you make an operation cheap, it changes how users perceive it.
joeerl:
- ‘thread pools are a failure of a language’
- X-oriented programming → x is cheap to make and user
make it cheap to create langauges
language oriented programming.
- enrich what
importdoes. - provides
- language extensions
- restrictions
- closure over libs
- and other first-order information.
flags are not composable.
inventing languages is natural, but programming langauges.. ad hoc, brittle implementations and unsafe composition.
seymor pappert - low floor and high ceilings.
#lang margrave - SAT SOlving, security policies
#lang scribble/base
new syntax - rhombus.
matthew flatt - macros are lightweight apis for compilers

- scene graph
- semantic prioritization
- frequency
