I haven't tested that thoroughly, but it looks OK. However, it doesn't
address the problem in this thread, which is that the OP wants to pass
the "more code" part to ssh on standard input.
A combination of your technique with what I wrote yesterday might be
viable, though.
{
declare -p password
cat <<'EOF'
more code
which uses "$password"
EOF
} | ssh user@host bash
That doesn't look too bad. The "incorrectly indented EOF" can be partly
solved with <<- if one uses literal tabs on the EOF line. Not all text
editors (or text editor configurations) like to do that, though.
