Description

Consider the following:

trait Foo {
  void bar() {
    print this
  }
}
"xxx".withTraits(Foo).bar() // prints String1_groovyProxy@328cf0e1

class Foo {
  String toString() {
    "foo"
  }
}
trait Bar {
  String getBaz() {
    this.toString()
  }
}
print(new Foo().withTraits(Bar).baz) // prints Foo2_groovyProxy@14b030a0

In the first example, I need to call a String method like "this.toLowerCase()" instead of "this" for it to work. I tried "this.toStirng()" but that fails as well, as illustrated in the second example.
