I guess by the last statement you meant that all objects that has 
attributes derived from _Signal are interfaces.
Obviously there are also list of signals.
How about dict of signals?
How about nesting, i.e. objects' attributes that are objects?
I hope there is a spec on supported features.

Btw, starting from Python2.2, new-style classes (derived from object) 
are just like built-in python types.
So you really need to scan everything of everything in an object to 
extract all possible symbols.
The Interface base-class idea was meant to simplify the scan. Of 
course, I only spent very little time on this, not sure if it's good or 
crappy idea.

Sorry I didn't catch the discussion on IntEnum. Any pointer to previous 
discussions in the mail archive?
