many builtin types can be called without arguments, yielding the 'false' (zero/empty) instance of their type. However, others can't. why is int()==0 but calling bool() raises an exception rather than returning False? I consider this irregularity a tiny bug. Arguably slice() should also return the same result as slice(None), again for regularity, but this is admittedly iffier.
