[swift-evolution] [Post Swift 3] [Proposal] Introducing `group` mechanism

[Adrian Zubarev]

How about adding attributes on extensions (just bikeshedding), because to me it’s not clear if you’re creating a class/static access label or for an instance of that type?

Nesting extensions would become useful for the sake of access labels.

struct A {
     
    public extension Self.foo {
        func someMethod() { … } // a.foo.someMethod()
    }    
     
    private extension Self.foo.bar {
        func someHiddenMethod() { … } // a.foo.bar.someHiddenMethod()  
    }
}

// Or
struct A {
     
    public extension self foo {
        func someMethod() { … } // a.foo.someMethod()
    }    
     
    private extension self.foo bar {
        func someHiddenMethod() { … } // a.foo.bar.someHiddenMethod()  
    }
}
The only problem I have with extensions, that they don’t read that well and personally I don’t like the default access modifier on them (not how its done right now).

Thank you for providing new ideas. :)
