[swift-evolution] Disambiguate Return Type With Void

[Vladimir.S]

Interesting suggestion, but IMO this will produce a question about new 
naming conversion in Swift 3.0 (noun/verb, -ing/-ed, etc) because using 
your suggestion we could want to use:

array.sort(..) // mutating
let array2 = array.sort(..) // non-mutating, instead of array.sorted()

Also, technically we can assign a value to Void function(yes, compiler 
warning will be produced, but just warning, not error):

var something = array.sort(..) // mutating,currently this is valid code
// something  == ()
