1d5e5aa735 Some type renaming in builtins 
Builtins will remain entirely separate from the actual type
representation, whatever that ends up being

2c298c7247 Add warning for undefined operator 
In practice this will probably always not typecheck, but it's a valid

0d13b5e3bc Preliminary support for binops in if-discriminators 
The BNF grammar is a bit more liberal than any successfully-compiled
schala program should be, in that it allows things like `if x < is
pattern`. It's okay if that parses successfully and then is an error at
typechecking.

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)
