[swift-evolution] [Idea] Custom default names for arguments of closures

[Patrick Gili]

Hi Eugene,

I think you'll be able to accomplish this with SE-0021 (https://github.com/apple/swift-evolution/blob/master/proposals/0021-generalized-naming.md <https://github.com/apple/swift-evolution/blob/master/proposals/0021-generalized-naming.md>), which has been accepted for Swift 2.2.

Cheers,
-Patrick
