Issue Description:
I’m not sure this is a bug or if this works as expected:
class Foo {
var name = "Default Name"
}
class Bar: Foo {
lazy var fullName: String = {
return super.name // error: 'super' cannot be used outside of class members
}()
}
Is there a good reason why super isn’t permitted here? Replacing super with self works fine, as I’d expect because the instance must be fully initialized when lazy properties are accessed.
