I don't know yet, when its safe or not to perform this optimization and if a rather simple test like now may detect all these cases. So for now, $HL could append a comment "#tail_call" after the prototyped specifier of the sub call. Then we can compare the debug output of $ parrot -Oc -d60 x.imc if both would do a tail call or not. > Sincerely, > > Michal J Wallace leo
