greg 348a6f7c76 More work on pattern-matching 
I think I need to entirely change the types in the evaluator.
ReducedAST should only care about NewConstructor (which I gotta rename),
and the evaluator is the only place that an implementation of a
primitive constructed type should live (see Peyton-Jones implementing a
functional langauge p. 70)

Note that symbol table is a different object now than the previous
binding table that was used for type-checking. That binding table is not
currently debugged and should be debugged in a separate debug output with
typechecking proper.
