Does anybody disagree that: $SHELL -c 'f() { (exit 3); return $( exit 1); } ; f; echo $?' should print "3"? The reason for the diverging behavior is the places where the shells implement checkpoints to save the current value of "exitcode" for the next expansion of $?. The Bourne Shell and it's childs have such a checkpoint at the end of the interpreter function and this function is called from the command substitution..... ksh88 removed one such checkpoint after the wait() for the $(cmd), but left the checkpoint in the interpreter function...
