In the caller docs, did you read this:
Furthermore, when called from within the DB package, caller returns more detailed information: it sets the list variable @DB::args to be the arguments with which the subroutine was invoked.
Also look (and/or use) Devel::Caller::Perl (which uses the "called within the DB package" technique) or Devel::Caller.
