TODO Items

• sketch of an idea for the REPL: -each compiler pass should be a (procedural?) macro like compiler_pass!("parse", dataproducts: ["ast", "parse_tree"], { match parsing::parse(INPUT) { Ok( PASS.add_artifact( }

-should have an Idris-like cast To From function

• REPL:
  • want to be able to do things like :doc Identifier, and have the language load up these definitions to the REPL

• change 'trait' to 'interface' -think about idris-related ideas of multiple implementations of a type for an interface (+ vs * impl for monoids, for preorder/inorder/postorder for Foldable)

• Share state between programming languages

• idea for Schala - scoped types - be able to define a quick enum type scoped to a function ro something, that only is meant to be used as a quick bespoke interface between two other things

• another idea, allow: type enum { type enum MySubVariant { SubVariant1, SubVariant2, etc. } Variant1(MySubVariant), Variant2(...), }

• idea for Schala: both currying and default arguments! ex. fn a(b: Int, c:Int, d:Int = 1) -> Int a(1,2) : Int a(1,2,d=2): Int a(,1,3) : Int -> Int a(1,2, c=): Int -> Int a(,,_) : Int -> Int -> Int -> Int

• AST : maybe replace the Expression type with "Ascription(TypeName, Box) nodes??
• parser: add a "debug" field to the Parser struct for all debug-related things

-scala-style html"dfasfsadf${}" string interpolations!

*Compiler passes architecture

-ProgrammingLanguageInterface defines a evaluate_in_repl() and evaluate_no_repl() functions -these take in a vec of CompilerPasses

struct CompilerPass { name: String, run: fn(PrevPass) -> NextPass }

-change "Type...." names in parser.rs to "Anno..." for non-collision with names in typechecking.rs

-get rid of code pertaining to compilation specifically, have a more generation notion of "execution type"
