in thread determine the variable causing the error: Use of uninitialized value

To rephrase it, your problem are undefined elements of data structures like $h{x}.

I don't think there is any out of the box solution and you'd need to send a feature request.

As a side note: a hack could be to add a signal handler which parses the OP tree at the caller for all undefined entries .

But that's far from trivial.

    Thank you for your suggestion Rolf, what should I do in order to send a feature request?
      I'm sorry but chances are too low, if you follow the discussion, especially the contributions by Dave_the_m you will see that is far too complicated too implement in core.

      update
      Anyway I've already shown code to help you in a pragmatic way
