Yes, that's fine. I'm not sure why you don't just use type(), though.
I'm not sure why you think type() is a substitute for __builtin__. Here's
a typical use-case for __builtin__:
import __builtin__
def map(*args): # shadow a built-in
# pre-processing goes here
result = __builtin__.map(*args)
# post-processing goes here
return result
How does type() help you?
It doesn't in that sense. The example that Benjamin elided used
__builtin__.type() for no discernible reason (unlike your example which creates
a shadow function that overrides the builtin version). Benjamin was asking what
the motivation was, since it was not evident.
