My wild aspirations in a nutshell:
Core enums: Any enum that's created without raw or associated values, e.g.
enum MyEnum {case This, That, Whatever, Etc}, can (and should) be Array<Self>
representable. This would add intrinsic ordering and raw value construction
starting with 0, up to count - 1. End-devs could use the ordering or not use
the ordering, but it would be possible to convert to bit representation (1 <<
this.rawValue), support iteration through the enumeration, introduce ranges
for switches, etc. A massive improvement.
Raw value enums: Any enum that uses raw values, e.g. enum ForExample: String
{case Hello = "hello", There = "there"} should be representable as Set<T>
Associated type enums: all bets are off
