My bikeshed is colored one of these:

At that point you might as well just use
import std.typecons : q = tuple, Q = Tuple;
Q!(int, int) foo(){
return q(1, 2);
}
If built-in tuples are not going to look like
(1, 2)
then imho we might as well leave them out,
But the banana syntax doesn't look bad:
(||)
(|1|)
(|1, 2|)
(|1, 2, 3|)
tuple()
tuple(1)
tuple(1, 2)
tuple(1, 2, 3)
also arguably enjoys the same advantages and in fact is much more
intuitive. Like, totally intuitive. Like, it says "tuple" to create a
tuple. And one advantage is, there's never ever going to be butt jokes
about tuple() as there'd be with "(||)".
It's short enough, it's not visually noisy, it's simple enough to
type, it consistently avoids the problems with literals for
0-tuples and 1-tuples, and it's sufficiently intuitive once you
have seen it one time. It's just a bit longer to type than the
syntax with simple (), that has problems with the shorter tuples.
The now dead Fortress language used several similar syntaxes,
like (|...|), {|...|}, [|...|], etc.
Well let's not take inspiration from dead languages :o).
