• Oil Startup

  • core/id_kind.py -- every token/entity in OSH/Oil
  • Lexer State machine can be frozen
  • Lexer regexes can be compiled to gotos (a la re2c)
  • OPy parse tables using pgen2 (but not the Oil parser)
  • ASDL schema
  • Builtin Flags and Help could be frozen
  • misc regexes: to validate variable names, etc.
