My vote is - when there's an overloaded function, put each version in

its own file.  And name the files something like

I would agree that's better if the dump order isn't deterministic.

However, it looks like an easy fix to make the dump order deterministic:

If the dump order is deterministic, I think its cleaner to put all versions in the same file.

Benefits:

+ Pretty looking filename

+ Same file structure for all object types, no special exception for functions

I think there's a merit to keeping all overloaded variations of a function in a single file, apart from the simplicity and benefits noted above. A change in one variation of the function may also be applicable to other variations, say in bug-fixes or enhancements. So keeping all variations in one file would make sense, since it is logically one object.
