I'm not convinced that an abstract NodeWalker is the best direction right now,
for two reasons:
1. Making tree traversal specific to the operation at hand (e.g., declaration
gathering doesn't visit as many nodes as variable access optimization) was a
substantial performance win, at least when it was first implemented.
2. The upcoming move to byte code will substantially change our AST needs in
unpredictable ways.
