I'd personally like to see a PEP.  It'd give people a chance to come up 
with some use cases that really justify adding such specialized dicts to 
the standard library.  The only use cases I can come up with would be 
better served by functions that take a sequence and produce a dict (e.g. 
by counting items or by grouping items into lists).  Once the dict is 
built, I usually have no more need for the default-specialized methods.

I'm sure there are some good use cases out there for such dicts, but 
before I get behind this, I wouldn't mind seeing a few of them. =)
