The __subclasses__ method is useful -- even more so in 3.x than in 2.x, 
because in 3.x there are no classic classes.

I was planning to make use of this in my generic function libraries to 
allow automatic checking for completeness and ambiguity of a ruleset, given 
the classes that are currently defined.  Currently, this is limited by the 
inability to access classic classes' subclasses, but in 3.x __subclasses__ 
is an ideal way to locate active classes.
