As I'm looking at adding builtins, it feels a bit like the types of args will end up scaling close to the number of semantic kinds. Rather than having this lead to a bunch of macros, this approach drops the macros for plain code. Note, this adds Get functions too -- I'd planned those regardless for type safety, this is just getting ahead of the issue so that the Print function is pretty clean.
