On second thought, the idea of "namespaces" within the interpreter
(like Tim Peters was suggesting I think in the doctest module) could
put some order to built-ins and globals within the interpreter.
round(), hex() and others could be in the namespace "Numbers" (Named
by their associated type), similarly for the other type-specific
Create a keyword "expose" to dump a particular namespace into the
global scope when you don't want to type "Numbers.round(f)".
