[swift-evolution] Colon vs. equals

To be clear, I like colon in parameter lists; I don't see passing a parameter as setting something.

I suppose mainly what I'd like is for attributes to change:

	@available(iOS, introduced: 7.0, deprecated: 8.0)

And *possibly* for dictionary literals to change:

	let dict = ["key" = "value"]	// Also, the shorthand syntax would be [String = String]

Although dictionary literals seem like a relatively high-impact change compared to its value.
