Description

I have 3 delegate clases:

class CommonDelegate {
    def String value = "CommonDelegate"
}

class CommonDelegate2 {
    def String value = "CommonDelegate2"
}

class CommonDelegate3 {
    def String value = "CommonDelegate3"
}

and a class Foo:

class Foo extends CommonDelegate {

    @Delegate
    def CommonDelegate2 commonDelegate2 = new CommonDelegate2()

    @Delegate
    def CommonDelegate3 commonDelegate3 = new CommonDelegate3()

}

Now, I run this code:

def Foo foo = new Foo()
println(foo.getValue())

And this prints "CommonDelegate2"

Question is now whether @Delegate should complain about the ambiguous call to getValue() in foo.getValue() as people expect @Delegate to be type-safe
