Also if you my message about the SIP issue, it appears that the PyQt 
core will not consider any overload it doesn't detect as being such at 
class creation time.

I almost clearly doubt, that attribute assignment will modify the class 
later on.

In general, it appears, that to overload you must use a class and for me 
unfortunately, it must be a pure Python function or method object at 
that point.

Enhancing sip to be able to track at run time the changes to the class 
appears possible. For consistency with Python it should be done, but the 
benefit, other than consistency with every other Python class, I admit, 
is dubious.
