I don't think it'd be easy. We could probably split
heap_{insert,delete,update} into sub-functions and then have the
toplevel function just loop over invocations of those, but that seems
like a pretty significant refactoring of the code. Since renaming the
labels isn't going to make that harder, I'm inclined to do that, rather
than wait for a refactoring that, while a good idea, isn't likely to
happen that soon.
