Hard to say. I can read the code and see that the current
implementation will always return objects of the same type. In fact,
it's using type(sre_compile.compile("", 0)) internally to represent
that type.
That's not a guarantee. Perhaps Fredrik wants to reserve the right to
change this in the future. It's not unusual for Python modules to be
under-specified in this way.
