[swift-evolution] Will these two features be included in Swift 3?

[Radosław Pietruszewski]

FWIW, I think most of the time it’s actually better to extend SequenceType rather than Array. I can’t think of many cases (for common code I would write), where an extension would be solely applicable to the Array type, and not all sequences (i.e. also array slices, etc.)

You can’t currently create an extension on Array<Double> so a common work-around is to add your functionality to SequenceType where you constrain the Generator’s Element to be of type Double - this means I’ve added functionality in places beyond where it belongs.
