[swift-evolution] Proposal: helpers for initializing properties of same name as parameters

[David Waite]

I don’t believe any more so than for let or var, which this effectively is a complement for.

func foo(var externalName internalName:String) { print(internalName) }

The local name has to match a parameter on the type. Like let/var (but unlike inout) usage of ‘set’ on a initializer parameter does not affect the caller or prototype conformance.
