Nope, it's just in __builtins__, and remains there whether you bind the same
name in the module scope or not. You can delete it from the module scope,
thereby making the one in __builtins__ visible once more.  And, as I pointed
out in an earlier posting, you can even bind __builtins__.None to a new
value if you want, to the confusion of all.
