Well I am hoping that few enough here know about CarpLevel to make telling them not to use it counter-productive. (Hey, what is that? Perhaps I can find a use for that even though tilly dislikes it...?)

As for an explanation of what I dislike, try this email and this followup.

As for finding your parents caller out of your own hierarchy, take a look in the current development snapshot at the implementation of Carp::Heavy. It solves that exact problem fairly efficiently.
