The behavior of `..` with heredoc has also interesting corner cases:
$ cat x.sh
cat <<END ; echo `echo a
echo b`
hello
END
$ dash x.sh
echo ba
x.sh: 3: x.sh: hello: not found
x.sh: 4: x.sh: END: not found
$ bash x.sh
hello
a b
$
On the one hand it reads heredoc, on the other hand it processes closing of the subshell.
