// Ensure we maintain compatibility with Swift 4's overload signature rules.
// Variables defined in extensions of generic types had different overload
// signatures to other variables, so allow overloading in such cases (SR-7341).
extension HasFooGeneric {
  var foo: String { return "" } // foo isn't defined in a generic extension in the other module, so allow overloading in Swift 4 mode.
  var bar: String { return "" } // bar is defined in a generic extension in the other module, so `bar: String` always shadows it.

// the other module never show up in the overload set.
