Ironically, your denial of a pretty clear case of ambiguity demonstrates 
that if anyone is confused, it is you.

In an earlier thread, Mario demonstrated an obvious example of confusing 
error message due to the object/instance ambiguity, where the error message 
states that Sub doesn't have a method when it actually does. It is an 
*instance of Sub*, not the Sub object itself, which lacks the method.
