• SR-2274 Nested functions should allow escaping attributes, be @NoEscape by default

Issue Description:

Consider this:

func funcPasser(f:@escaping ()->()) -> () -> () {
    return f
}
class MyClass {
    var name = "matt"
    func test() {
        func f() {
            print(name)
        }
        let f2 = funcPasser(f:f)
        f2()
    }
}

Now, maybe I'm wrong, but it seems to me that the compiler should be complaining about the bare `name`. It should be insisting that I say `self.name`. I am handling `f` in a way that will capture `self` and preserve it, and the compiler knows this, because `funcPasser` has a `@escaping` parameter. If this were an anonymous trailing closure, the compiler would insist that I say `self`, so why doesn't it insist on it here?
