[swift-evolution] Consolidate Code for Each Case in Enum

[Jay Abbott]

Thanks for pointing this out Tim. I had actually read the whole thread but
over a few days between other things and must have missed the relevant
updates.

I think you may be reacting to the very first draft. `extension` isn't used
> at all in the newest draft, and no code can exist outside the enum. In
> fact, there's a fair amount of similarity to your idea in the newest
> proposal.

Oh yes - this is much better! Lovely in fact. Although it does lose the
benefit of at-a-glance understanding of the cases present in the enum when
they are on one line each (when the code gets bigger than in the example
they will be quite a way apart).
