I'm not sure how much you can do with typing. Things like heap_getattr
are macros, and thus untyped. Most places use attr as an index to an
array, which also can't be type checked.

If you switched everything over to inline functions you might get it to
work, but that's about it.

IMHO the best solution is to offset the logical numbers by some
