[swift-evolution] [Idea] `enum` case count feature

[Nicholas Maccharoli]

Swift-Evolution,

I'm sorry if this has been brought up before but is there a reason why
there is no built-in way of getting the number of cases an enum defines?

Given something like: enum MyEnum { case foo, bar, baz }

It would be nice to get the number of cases this enum defines, something
like:

    MyEnum.count

Looking forward to hearing back about this!
