[swift-evolution] [Discussion] Determining argument count from context

[Paul Cantrell]

This is filed here:

    https://bugs.swift.org/browse/SR-586

There was some discussion about it on the list about whether this is a bug or a dubious feature. Douglas Gregor recently weighed in on that:

> I consider this a bug. The removal of implicit tuple splats should, IMO, encompass making $0 consistently capture the first argument. I’d love for this to happen in Swift 3.
