[swift-evolution] [Discussion] Generic protocols

I just overlooked that the subsection about generic protocols was inside the Unlikely section.

The problem is that I need a way to refer to a function with a specific name. Plus the connection type has to have a specific API, like having a DispatchQueue and know the router object if there is any (sounds like a protocol right?!). The function reference should also keep the connection object alive with a strong reference.

associatedtype does not solve that problem for me.

I clearly see that generic protocols overlap with associatedtype but couldn’t we find a compromise here? For instance like Chris Lattner introduced generic type aliases without the ability of constants.

Aren't protocols generic already using
Not really:
Take a look at (for example) AnyIterator… this whole layer of indirection could be removed with the requested change.
You can declare a protocol that generates Ints, Strings or whatever you like — just not in a generic way, and that's a pity.
