[swift-evolution] Colon vs. equals

Afaics, the equal sign is way more common to assign values to parameters — but as Objective-C and Swift have labels, colon fits better (some labels don't make good variable names)

A name, parenthesis, names for parameters except the first… looks very much like a function call, so I agree, colon fits better.

I think the equal sign should only be used for assignment (as it was decided to keep a C-tradition and not use it for comparison).
"Key" and "label" are very similar to me, so I prefer label syntax.
