Cute, but uh, I'd much rather see tuples just be returnable.
They are.
template Tuple(T...)
{
alias T Tuple;
}
Tuple!(int, float) foo()
{
return Tuple!(3, 4.5);
}
foo.d(10): Error: functions cannot return a tuple
Unless you're using some prerelease compiler, they are not.
import std.typecons;
Tuple!(int, float) foo()
{
return tuple(2, 4.5);
}
The addition of the alias this feature and of constructor templates
makes std.typecons.Tuple even better.
