"HandleError" (code ref, inherited)
   The "HandleError" attribute can be used to provide
   your own alternative behaviour in case of errors. If
   set to a reference to a subroutine then that
   subroutine is called when an error is detected (at the
   same point that "RaiseError" and "PrintError" are
   handled).

   The subroutine is called with three parameters: the
   error message string that "RaiseError" and
   "PrintError" would use, the DBI handle being used, and
   the first value being returned by the method that
   failed (typically undef).

   If the subroutine returns a false value then the
   "RaiseError" and/or "PrintError" attributes are
   checked and acted upon as normal.
