[swift-evolution] Pre-proposal: CaseEnumerable protocol (derived collection of enum cases)

[Denis Nikitenko]

For the protocol name, I rather like FiniteType (or FiniteValueType), since I find it to be more general and future-proof.  ValueEnumerable would also work, though.  

My preference for the static var would be T.values or T.allValues - we want to get all values of the finite type T.

Definitely a +1 on the overall proposal.
