Just my $0.02: I occasionally wish we had Py_RETURN_BOOL(1/0) instead
of Py_RETURN_TRUE/FALSE, but I feel proposed Py_RETURN() is too
ambiguous and should be called Py_RETURN_SINGLETON() or
Py_RETURN_NEWREF().  Longer spelling, however makes it less
attractive.  Overall, I am -1 on Py_RETURN().  Introducing the second
obvious way to spell Py_RETURN_NONE/TRUE/FALSE will clutter the API
and novices may be misled into always using Py_RETURN(x) instead of
return x attracting reference leaks.
