I was going to mention that. I think it still needs some work --- which
I know how to do in this case. N.B. you can test this with the line
[ x$ZSH_VERSION != x ] && emulate sh
at the top of the "code" variable.
However, I'm trying to work out what happens with the case
| trap '(exit BEFORE-RETURN); return EXPLICIT-RETURN-VALUE' SIGNAL
|
| fn() {
| (exit BEFORE-ACTION); -block here waiting for signal-
| }
Should this exit with EXPLICIT-RETURN_VALUE or BEFORE-ACTION? The
latter is easier to implement but my guess (without ploughing through
the standard) is EXPLICIT-RETURN-VALUE is right here.
