Issue Description:

The following code compiles with Swift 4.0, but not with Swift 4.1 beta (Xcode 9.3 beta 4)

extension Sequence where Iterator.Element: AnyObject { 
    public func containsObjectIdentical(to object: AnyObject) -> Bool { 
        return contains { $0 === object } 
    } 
}

The following change mitigates the issue and compiles both in Swift 4.0 and Swift 4.1

extension Sequence where Element: AnyObject {
    public func containsObjectIdentical(to object: AnyObject) -> Bool {
        return contains { $0 === object }
    }
}

Can't see any reason why the original shouldn't work. Thanks, Luca!

This seems to have been fixed on master, so I added a regression test: #15786

lucatorella (JIRA User), Could you verify if the problem is fixed and if so move the JIRA to "Closed"?
Thanks!

I confirm it’s fixed. Both version work in 4.1.2 and 4.2. Closing now. Thanks!
