[swift-evolution] Proposal: Enum 'count' functionality

[Jacob Bandes-Storch]

I brought up this topic a couple weeks ago in a thread called "List of all
Enum values (for simple enums)":

https://lists.swift.org/pipermail/swift-evolution/Week-of-Mon-20151207/001233.html

I suppose it's time to start synthesizing those ideas/discussion into a
proposal :)
