Twylite already answered my question, and he also gave better reasons
than that one, so I declared my defeat on this topic already. ;-)

Without the intention to reopen the discussion, with per handler
variable lists, not only do I not know what a variable really 
contains (error-message or return-value), but also don't know
which variables were actually set in the try.

PS: I'd have called the variable "retval" or just "rv" instead of 
  "xxx"   and would probably do so if an "as ..." clause is ever
  added as optional clause, later.

PPS: most of the cases, I'd place the "on ok"-body right into the
  try-body, so the different interpretation of the variable would
  not be a problem most of the times.
