Timon Gehr:
My bikeshed is colored one of these:
(:1,2)
(|1,2)
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|)
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.
