• remove * in type variables
• pattern matching/destructuring
  • Change list destructuring to use .. and remove as Lists: [a, b, c] or [a, b, .., d] or [a, b, c, ..d] (not .. as d)
  • Change record destructuring to support .. {a, b, ..} or {a, b, ..rest}

Notes on performance:

disabling the "prefixed_expr" massively reduces the sizeof the parser. infact it almost halves it

later:

• for loop syntax
  • What do i actually need for this?
• custom record/nominal types syntax
• static dispatch syntax
  • .method() invocation
  • new autoderive syntax
  • remove abilities (probably put this off for a bit)
