Darn! It's so obvious :-). I would suggest using "cdd" instead of "cd" since
pushd/popd will change drives, too. Another possibility, which is more csh-like
is to allow for "pushd", no arguments, to swap:

alias pushd=`iff "%1"=="" then^set d1=%_cwd^popd^set d2=%_cwd^cd %d1^*pushd %d2^unset d1 d2^else^*pushd %1^endiff`

I haven't tried this yet, but it should work.
