Cool!  I was also worried I was getting some circular references so
that should minimize them.

Would it be possible to actually print that out?

"Wrong argument type:
 You called:
        foo(int,QRect,QColor)
 when only the following are supported:
 	foo(int,QObject, QColor)
 	foo(int,QRect, QWidget)"

I'd guess in the 2nd half, sip could handle that as just a standard
message/string for each function.  That might also have general
usefulness as some simple documentation.

The first half you'd have to actually have code looping through the
arguments and printing out their type -- which I don't know how
difficult and error prone that would be.  On the plus side, it
wouldn't represent any runtime overhead since the code would only
execute when the wrong argument types are passed.

Boy, it sure is fun to suggest work for someone else to do :-)
