Is tuple required to be anonymous struct? I thought it's
implementation details that may be done the other way if tuples
implemented in language rather then library. There's another
problem with non-named return values, as this:
auto (sin_a, cos_a) = sincos( a );
is not equivalent to this:
auto (cos_a, sin_a) = sincos( a );
I can't imagine a syntax that's non-destructive to the existing
grammar where order is not important, but order would be clearly
stated in the auto-complete pop-up, and in the reference. Also
mismatching types would throw errors.
You can't mess with the parameters order in this case:

Is it impossible to make efficient multiple return values without the
need to trade off the help from tools?
