$(...) and <<

$ zsh -c 'echo $(cat << EOF
blah)
EOF
); echo test'
zsh:4: parse error near `)'

Most shells (ash being a notable exception) used to suffer from that bug.

zsh seems to be the only one nowadays (tested ksh93/bash/dash/yash/mksh).

By the way, is there  any plan of having an issue tracker for
zsh somewhere. That would help to keep track of the known
issues.
