I disagree with dropping function references in general, but I do agree
with limiting partially applied method references.
In @escaping arguments, adding self. won’t add enough evidence that it
actually creates a closure with capture.
Even in non-escaping context, I find plain method references odd:
func square(_ x: Int) -> Int { … }
(1...10).map(square) // totally ok with that
class SomeClass {
func foo(_ x: Int) -> Int { … }
func bar() {
(1...10).map(foo) // what??
(1...10).map(self.foo) // ok
someControl.addHandler(self.foo) // should be error if @escaping?
}
}

I encountered this precise memory leak in my code a few days ago, so I
