As promised [1], I have started setting up a DIP to improve tuple

Oh Yes!
Question, would named tuples be able to be worked in or is that way out
of scope? I.e. something for this use case:
alias Color = Tuple!(int, "r", int, "g", int, "b");
Color f(Color input);
auto color = f(Color(1, 2, 3));
writeln(color.r);
Very handy with general graphics stuff, Point, Vector, etc
Or for getting enumerate type functionality?
range.enumerate() // Tuple!(int, "index", T, "value)
So would we be able to work in something like:
(r: int, g: int, b: int) f(int r, int g, int b) {
return (100, 200, 150);
}
// Or more consistent with function syntax?
(int r, int g, int b) f(int r, int g, int b) {
return (100, 200, 150);
}
// And how about auto return named tuples?
auto f(int r, int g, int b) {
return (r: 100, g: 200, z: 150);
}
My thoughts were:
http://forum.dlang.org/post/p3e4al$1jfc$1...@digitalmars.com
But as it has been requested more than once and it is a feature of
existing Phobos tuples, I can add a proposal to the DIP that can be
accepted/rejected independently, and add a few words to the
"limitations" section.
