Quick question? Is PEP 8 still current for what is being done in Py3.x?
I just took a quick look and it says:
Class Names
Almost without exception, class names use the CapWords convention.
Classes for internal use have a leading underscore in addition.

Unfortunately PEP 8 never really took off naming-wise, so we're mostly

the "reuse the naming scheme from existing code in the same module" rule,

think there lowercase wins, thanks to defaultdict.
Traditionally, the all lowercase name referred to a C type. The other
classes in
collections are named Counter, UserDict, UserList, UserString,
MutableMapping, etc.
Besides, the lowercase/uppercase distinction helps us distinguish functions
from classes.
This is the way I've see every Python book do it since the dawn of time.
Then they're all wrong. In 3.0 we're moving away from this, e.g.
cPickle is gone, so is cStringIO. The implementation language should
not shine through. *Maybe* the "built-in status" should guide the
capitalization, so only built-in types are lowercase (str, int, dict
etc.).
Anyway, it seems the collections module in particular is already
internally inconsistent -- NamedTuple vs. defaultdict. In a sense
defaultdict is the odd one out here, since these are things you import
from some module, they're not built-in. Maybe it should be renamed to
NamedDict?
