[swift-users] tuples and metatypes

[Ray Fix]

Hi. Asking for a friend ;]

Tuples cannot conform to protocols or be extended because they are compound types. Is it correct to say that this is true because there is not a unique metatype for  compound types?  IOW, there is no unique existential container thingy for a tuples?  (Not sure if I am using the proper vocabulary here or not.)

Thanks for your thoughts,
