[Python-Dev] Classes that claim to be defined in __builtin__ but aren't

The real question seems to be whether __builtin__ should contain *all*
built-in types, including internal ones, or only those intended for
public use. Do you have an opinion about that, Guido?

I suppose it's reasonable to put them all in __builtin__, since as you
say, they can be useful for type checking even if you can't or rarely
want to instantiate them yourself.
