Because it did not work in general. I don't recall the specifics, but it should be there in the discussion of it.

Parameter packs is a last resort, so well written code will not use it all that often. If ... worked with all sequences then it would make more sense. C++ has too many special cases and D does not need more special cases either. (Folding with subtraction is also problematic.) | |||

Also, you can implement you own fold in D. Have you looked at Haskell? It has some of that beauty of dancing with handcuffs. | |||

It means Ok, I misunderstood. I think proper tuples that can hold both types and values is the best approach, then add operators on tuples. C++ and D got it wrong by having some weird special cases for parameters, which is just annoying. Cannot be fixed for C++, but it is fixable for D. Solid and generally useful tuples is the only basic feature D is missing (and move semantics, but not sure if that qualifies as basic). | |||
