Add another future feature to the readme
Just discard whitespace in the lexer, no reason to keep it. Also convert some vecs to slices.
Make a CompileError type that contains the position in the source that the error occured at.
Make the Token type include a source position as well.
Improve some error messages.
Update to latest rust.
Refactor.
Make lexer accept more constant literals. (see examples/expr.synt)
And probably something else I forgot
