Is it possible to call an overridden method from self type?

Question

Consider this:

 class Foo { def foo = \"foo\" }
 trait Bar { self: Foo =>
    override def foo = \"bar\"
 }

I was pleasantly surprised

Answer 1

You make your trait extend Foo instead of using the self type:

class Foo {def foo = "foo"}
trait Bar extends Foo {
  override def foo = super.foo + "bar"
}
new Foo with Bar foo // barfoo
