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 shorter than q()
it's not visually noisy,
It adds more noise than q()
it's simple enough to type,
It is harder to type than q().
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.
I still think any built-in special syntax that differs from (1,2,3) is not worth it.
The now dead Fortress language used several similar syntaxes,
like (|...|), {|...|}, [|...|], etc.
