Comment (by ncohen):
> I would like it for sure if its purpose was only to return a boolean! A
function that starts with `is` must return a boolean, otherwise it is a
mess:
> {{{
> if m.is_even():
> print "m is even"
> }}}
> bad luck: `.is_even()` return a pair "(boolean, m divided by 2)"
(remember the concrete example in #16464).
`return_parameters=True`...
> It is implemented, not very ugly and not very useful!
What about all the stuff you converted to tuples ?..
