There are many more places that don't accept 64 bit numbers. And
for most of them, there's no single best way to handle this (e.g.
for C functions bound via the classic Lua/C API). The 'for' loop
handling is already quite complicated internally and I don't want
to add more complexity.

Oh, and: the JIT compiler happily optimizes tonumber(number) away.
