Allow assigning to constants

[cgccuser]

Why should 1 always be 1? Why can True never be False? Why can None never be "everything"? These arbitrary, fascist rules must not be enforced any longer. The Python developers may never listen to me, but I hope that the open-minded folks at Whython will. I propose allowing users to assign values to constants/literals/whatever they're called. No longer should "bad" = "good" be an error! It should replace all occurrences of the string bad with good later in the program. Likewise for numbers and stuff.

Not sure this is really possible...

Perhaps you could replace every constant/literal with get_literal_or_previously_assigned_value("foo") and have a dictionary of these previously assigned "constants."

Ooh, that's an excellent hack!
