Summary: builtin type inconsistency

Initial Comment:
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.
