Overall, -1.
I agree that labels should not affect the type, but imho the current status
(Swift 2.3 — I haven't checked Version 3) is fine, and the proposal doesn't
achieve what it says in the title:
For me, that is no question of types at all, but only of names:
var a: (Int, z: Int) -> Void = t
var b: (y: Int, z: Int) -> Void = t
a = b
This works, because a and b are both of type (Int, Int) -> Void, and the labels
aren't significant.
So the proposal merely disallows labels in the declaration of function
variables, which I consider bad, because labels convey the meaning of
parameters. Why should something that is widely seen as a good feature of
functions be removed from function variables?
If you share the opinion that labels are part of the name, the battleship
example no good argument against labels:
No one stops you from doing
let minimum: (Int, Int) -> Int = max
Which is confusing as well.
Best regards,
Tino
