[swift-users] did i just imagine tuples were going to be hashable in swift 4?

Here what I can find regarding your question:

we can't have [(type1,type2):type3] in Swift without declaration of new temporary 
struct type and implement Equatable&Hashable for it.

It would be reasonable, IMO, even before we support the full generalization of 
extensions on non-nominal types, to make tuples of Equatable/Hashable/Comparable 
elements conform to the same protocols by fiat.

So... it seems like we all (including core team) want this, but this will not be 
implemented in Swift4, as I understand.
