I'm guessing you'd end up with some weird rules

z = foo(); // what is z, a tuple, or y?

auto (a,b) = ((1,2),(3,4)); // eh, what is this?

foo((1,2)); // um, what?

When offered semantic ambiguity, just say no.

How about this?

OtherTypeIwant foo(out bool flag){...}

...

while(guardflag && (x=foo(f), f)){
...
}


Just checked, still have something like this in my code.
