In my "cratification" PR, I have been making things aggressively private. This causes stack overflow. It's weird.

…B of stack unconditionally. This is prompted by some sort of bug in trans that causes a stack overflow when the modules in trans are made private. (In particular, the overflow can also be avoided by making `controlflow` and `callee` public, but that seems strictly worse than just using more stack.)
