`for f in $(a; b); do :; done` not supported about bashlex

Can you give a complete example? One of the links on the front page is

for user in $(cut -f1 -d: /etc/passwd); do crontab -u $user -l 2>/dev/null;
done

( IFS=/; set -ef -- /D/a-b*; for f in $(ls -rtd "$@"; echo /); do [ -n "${f##D*}" ] || continue; mv "${1%/*}/${f%?}" "/r${1%/*}-a"; done ).

Sorry for making such premature conclusion on the title.

Tracked down to for f in $(a; b); do :; done. Updating title..

It seems like any command substitution with a comma doesn't work, even $(a; b).

[Artoria2e5]

Hmm. Backtick ones work though.

Yeah, I'll have to walk through the code with a debugger to see what's wrong. ETA: unknown. :(

Wow.
