It's not necessary to quote a variable on the right-hand side of an

I'm not sure I entirely approve of that, because it seems to make the
syntax less regular, and I'll continue to quote them in my own
code... but 'declare -f "$old"' and 'unset -f "$old"' seem no-brainers.
Also, I decided I didn't care about any brokenness resulting from
however the user might have managed to persuade the shell to create a
function with a non-identifier-syntax name.
I'm more coming from the point of view of never writing scripts that
expose a quoting attack, even if you never think they should ever be
exposed to untrusted strings.
