[swift-evolution] [Pitch] Non-class type requirements on protocols (eg : struct, : enum)

[Tino Heth]

As this discussion pops up again:
Am I the only one who dislikes the missing capitalization?
I don't see any value in recycling a keyword (and breaking with convention).

Imho it should be
protocol StructOnlyProtocol: Struct {
and
protocol ClassOnlyProtocol: Class {
