That's fine, but you're not avoiding all of the Python
call overhead that way. You still need to build a Python
argument tuple to pass to the __new__ method.

Also, keep in mind that interpreted code can bypass
the __init__ method in the same way, by calling the
__new__ method of the type. So your technique is not
completely crash-proof, although it would require
going out of your way a little to provoke one.
