We have figured out aliases for cd, pushd and popd that make the directory
stack available in a shell variable.  This means that you can:
cp file $ds[2]
to copy a file to the directory you would be in if you then did popd.
Not only that, but the directory stack can be inherited by subshells!

If this generates interest, I will post to net.sources.
