I'm not sure if that diagnosis is correct, look at this:
% { print XXX; return 0; } >| /tmp/newfile; echo hello; print $(</tmp/newfile)

and if you put a sleep 10 in there, it still completes immediately,
ie, does the return just return from the whole statement? Isn't that
actually expected since it's not in a function or subshell?
