[swift-evolution] Dotless case names in switch cases

[Jens Persson]

I see, I never thought of the case names as being instance-member-like, and
I thought it would be simpler to just  have one form for the switch cases
(the one with a dot before the case name).

I don't want the dotless form to be removed if it complicates rather than
simplifies the (compiler) code.
