Issue Description:

Xcode does not complete static operator implementations. For example:

struct Foo: Comparable {

*static* *func* fooify(\_\_\_ string: String) -\> String {

    *return* "foo"

}

*static* *func* ==(lhs: Foo, rhs: Foo) -\> Bool { *return* *true* }

*static* *func* \<(lhs: Foo, rhs: Foo) -\> Bool { *return* *true* }

}

typealias Fooquatable = (Foo, Foo) -> Bool

![](Screen Shot 2018-03-09 at 8.44.55 AM.png)

Neither `==` nor `<` is listed and you cannot refer to `Foo.==` or `Foo.<` in code.

This is not really a code completion bug, because you can't use that syntax anywhere at the moment!

This is a quick brain-dump I did last weekend on how I think we can fix expression type checking times for expressions involving operators. Although it doesn't (yet) explicitly mention support for explicit operator references like this, I was intending on fleshing out the details to explicitly support that as well: https://github.com/rudkx/swift-evolution/blob/operators-as-members/proposals/9999-operators-as-members.md
