While I was unclear, you missed the context

I did read all of your post, twice in fact, and a third time now (did you edit it?), and I'm sorry, but I still don't understand the point you're trying to make here - how is a utility that munges mys related to anything I said? Anyway, since you're talking about deficiencies, i.e. things that could potentially be considered bugs, I think that it would be better if you could show with runnable code what exactly the issues are that you are having - a Short, Self-Contained, Correct Example.

Please look at Re^2: What's happening in this expression? (Updated)
