Summary: remove/discard method for dict objects.

Initial Comment:
dict objects already provide a method for getting from

the dictionary (possibly returning a default value) so

as to avoid raising KeyError.  But there's no way to

remove an item that may or may not be in a dictionary

from a dictionary without risking raising KeyError.



I think there should be a method to remove a key if it

is in the dictionary, but to do nothing if it isn't. 

I'd suggest calling it .remove, but the sets.Set type

offers this functionality as .discard, so perhaps

that's a better name.
