[swift-evolution] ternary operator ?: suggestion

[Paul Ossenbruggen]

All,

I think, I finally might have the answer to improving ternary, with such a bold statement come some pretty high expectations but I think, I might actually have done it this time :-)

I am calling it the Demux Expression, it builds on the benefits of ternary and switch while improving on those.

This is a first draft, thanks in advance for feedback!
