Comment (by jason):
What's the current status?
Just the other day, I would have loved an iterator that would iterate
through a gray code and tell me just the element that changed and by how
much, so I could do:
{{{
for i in myiter():
# i is the thing that changed, so I can update my data structure
accordingly, and just have to change one thing
# some other code depending on the current status of my data structure
}}}
