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

[Dan Appel]

I'm not sure how I feel about this, but in either case, why limit it to
default parameters? It's useful in other situations, too.

Take this for example:
struct Foo {
    let bar: String
    let bas: Int
    let baz: Double
    init(self.bar: String, self.bas: Int, bax: Int) {
        self.baz = Double(bax)
    }
}

where the need to say

self.bar = bar
self.bas = bas

is now avoided.
