You're conflating two separate issues. The existing alternative 
to using a TypeBuilder + iteration is `static foreach`--which is 
also iterative.

The question you should answer, if you want to convince people 
that TypeBuilder (or something like it) is worth adding, is "how 
is this better than `static foreach` and `static if`?"
