I like WeakKeyDict and WeakValDict because the existing names
seem excessively long-winded, given that 'dict' or 'Dict' is
a well-established abbreviation.

But I actually think that at least some of the weakref stuff
should be builtin, seeing as support for it is wired directly
into the core implementation. In that case, all-lowercase
names would be more appropriate.
