[swift-evolution] [Idea] Passing an Array to Variadic Functions

Afaics, this isn't true:
Increment/decrement operators, currying, tuple splat and even the C-style for loop have already been deprecated, and although I would have preferred to keep some of those constructs, I think it is good how progressive Swift is pushed forward ("would we add this feature now if it wasn't already there?").

The value of variadic functions is imho less than the possibility to omit "()" in procedure calls, and afair, there have been several posts that illustrate the complications of this feature.
