It also means that things like the `Token` type end up carying a `String` by value and paying for things like reference-counting. This change adds a `Name` type that is used to represent names of variables, types, macros, etc. Names are cached and unique'd globally for a session, and the string-to-name mapping gets done during lexing. From that point on, most mapping is from pointers, which should make all the various table lookups faster. More importantly (possibly), this brings us one step closer to being able to pool-allocate the AST nodes.
