Add guard to Alternative
...
The semantics are:
-if tag is Some(_), assume the condition is a constructor,
and compare tags
- if guard is Some(_), evaluate true/false *after* having
applied any bound variables
With this, I can technically get rid of bare conditionals now, since
they are the same as an Alternative with a None tag

The BNF grammar is a bit more liberal than any successfully-compiled

typechecking.

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)
