c64f53a050 Detect duplicate variable declarations correctly
Later I'll probably want to make it so that you can explicitly override
the value of a declared variable

0bcd7e6f41 Add new_env method
This is basically the same as the one on the evaluator and makes use of
the ScopeStack - maybe need to generalize this more?

9bb3a2be88 Add type data handle on Node
I think the way I want to handle this is a two-step process: first infer and
fill in variables, then unfiy in a separate step. Storing the data in
the AST is handy.

Doesn't seem to conflict with the same macro in the parser tests, so should be

06e9452718 More type infrastructure
From here on out, I can start playing with concrete code that attempts
to actually typecheck limited syntactic constructs, and see what I end
up with.
