[swift-evolution] Proposal SE-0009 Reconsideration

[Vladimir.S]

Oh, in this case IMO warning for 'self.' will never be introduced, it's 
clear. And as I understand, no support in community for warning for 
shadowing. OK, so as I understand, the only solution here - tools like 
SwiftLint and plugins to xcode.

Btw, regarding 'similar to the override keyword', do you mean something 
like this:

class A {
   public var x = 10

   func f() {
     override var x = 100

     var value: Int? = 1
     if override let value = value {..}
   }
}

?
