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.

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.
