[swift-evolution] ternary operator ?: suggestion

[Charles Constant]

Paul, my preference is for the shorter ones - whether yours, mine, others.
I don't think that verbosity (even using "case") is better suited to this
ternary/switch proposal.

Verbosity only makes sense when the payoff is more clarity. But what the
proposal we're all discussing is for, is to simplify a choice between cases
in a list - possibly *dozens* of cases.

If it made sense to be verbose here, then why not also be verbose when
creating Dicts or Arrays?

Hope this makes sense.
