Not every one line expression needs to be a function in a library. `bool(getrandbits(1))` is self-explanatory enough, and it is doubtful that any implementation would be faster.

Using getrandbits(1) to return 0 or 1 is fine; if you need a bool, call bool on the result.

Aside: the name getrandbits is a bit sad, there's no setrandbits and we don't name the other random functions with a leading "get" prefix:

    getrandint(1, 6)


Raymond, would you consider providing an alias randbits and depreciating the getrandbits name? We don't have to remove it, just document it as depreciated to be removed in Python 5000 :-)
