I'm neither a Smalltalk, C++ or Objective C programmer. How is a bag
different from a set? In my GE days (pre-Python) we had a collection class
in a proprietary language which was used as a proxy. You'd send a message
to the collection and it would forward it to all the elements it contained.
This was rather convenient. You could tell all the actors to turn and face
the camera, for example.
Oddly enough, although we used collections heavily, I never really missed
that functionality in Python. I implemented it once or twice, but never
used it much. Different style of programming I guess.
