- Everything is different now
- Builtins are now built on top of Rust functions, so they can be recursive!
- TODO: allow macro-defined builtins to call each other?
- The builtins! macro is a lot nicer to work with
- No redundant return value
- Maps the result over Into::into, allowing for type inference!
- Uses explicit pattern syntax instead of weird binding, where possible
- Does not #[allow(unused)], so you'll get unused variable warnings now!
- Integrate the Match and Pattern nodes into the AST
- TODO: `let x: T` is ambiguous with `let x: {}`. Currently the latter takes precedence in the parser.
- Implement pattern matching through unification in the interpreter.
- It's not fast, but it works!
- Refactor destructuring assignments to use the new pattern functionality
- Smuggle floats as integers to maintain `eq`
- This is bad, but not terrible for spec-compliant floats. Might have issues with NaN.
cl_parser: Smuggle floats
cl_interpret: unpack smuggled floats in float literal node
grammar:
- Improve specification of `Path`
- Add `Use` and `UseTree` rules
- Add `Use` as a variant of ItemKind
cl-token:
- Add new keywords `use` and `as`
cl-ast:
- Add nodes for Use and UseTree
- Add new ItemKind for Use
- Implement traversal in Visit and Fold
cl-interpret:
- Mark ItemKind::Use with a todo
cl-parser:
- Update to match grammar
cl-typeck:
- Update to match changes in AST
- Mark UseTrees as NameCollectable and TypeResolvable, but leave as todos
