Add a short discourse on the Types, and provide a Bottom type.
Make a final toString; require each Node to specify its special printing via label().
Add a recursing printer called print(); toString is used by default in the debugger and so cannot be recursive.
Make the peephole rules based on a proper Type and idealize calls.
Big comments about the Type computations.
Every node picks up a _print, compute and idealize() call.
Rename long arith ops Divide, UnaryMinus, Multiply, Subtract into shorter uniform-length names. Cleans up the parser where he does the precedence op parsing.
Rework Parser:
- Drop Token class, its all Strings except in the one place we know a number is coming
- Embed the Lexer as a field in the Parser, instead of trying to pass it around everywhere in the Parser
- StartNode becomes a read-only global, so we don't have to pass it around everywhere in the Parser AND optimizer.
- Lexer matches on strings and returns strings. Match and consume *at the moment* instead of carrying around a current token/string and forcing the next-token after consuming the current one.
- All parse subexpressions shrink by 1/2 after these changes.
