cl-token:
- Minimize data redundancy by consolidating TokenKind::Literal; TokenData::{String, Identifier}
- Rename Op to Punct
cl-ast:
- Remove ExprKind::{Member, Call} in favor of making them
'binary' operators
- Consolidate boxes (TODO: consolidate more boxes)
- Remove repetition vecs in favor of boxes (this may come with performance tradeoffs!)
cl-lexer:
- Reflect changes from cl-token
cl-interpret, cl-repl/src/examples:
- Reflect changes from cl-ast
cl-parser:
- Switch to Pratt parsing for expressions
- TODO: Code cleanup
- TODO: Use total ordering for Precedence instead of binding powers (that's what the binding powers are there for anyway)
- Switch functional parsers to take Punct instead of TokenKind
- It's not like we need a `for`-separated list
- Remove `binary` macro. No longer needed with precedence climbing.
- Repurpose `operator` macro to produce both the operator and the respective Precedence
- Remove several of the smaller parser functions, since they've been consolidated into the larger `exprkind`
