You can find this out from the error, which says that you can't expand an object of type `(Tuple!(int, int))`. Note the surrounding parenthesis: they tell you that what you have is not a Tuple, but an AliasSeq whose only member is a Tuple. If you do `[0]` on it, you obtain the correct type, i.e. `Tuple!(int, int)`, without the parenthesis.
Ah.
