FWIW I'm certain that the lack of tuples in Go was a very deliberate decision - one of Go's more significant ancestors, Limbo, had tuples. Anonymous product types have their disadvantages too (you don't get to name the members, so code can end up significantly harder to understand), which I suspect is why Go didn't get them.

I believe that the new register calling convention will do this for structs FWIW.
