Swift generics: copying and pasting my code for T? so that it can also work for [T], instead of writing it once with id.

@mjtsai Optional and Array both fit in an Any…

@jckarter Is there a way to compare to Anys that I know are both Equatable inside?

@mjtsai The generics features we're planning for after 3.0 should make it easier to work with Any and other dynamic types.

@jckarter That would be nice. Right now, Any is hard to do much with.

@mjtsai With some helper functions, you can get pretty lightweight syntax for forcing Any into static contexts: https://gist.github.com/jckarter/2762c4fe91d8eba4b1ce27060b4c601d …

@jckarter That is wild. How is it that if x is a Derived and I do (x=>Base.f)() it ends up calling Derived.f()?

@mjtsai Base.f doesn't pick a method implementation until you give it a `self` parameter.

@jckarter Aha, I was used to the way Python does it. Good to know. Can you do that with an operator or only a named method?
Joe Groff ‏@jckarter May 24

@mjtsai The way method references are "curried" means you'd need a separate overload for => taking (T, U) -> V functions…

@jckarter I was more thinking about getting a method reference from an operator. For example, I can write Int.successor but not Int.+ or +
