Stephane is correct.  It's actually a bug which I occasionally tickle. 
I've just never been motivated to do anything about it.

The bug is when I would try to p(ush)d to a directory that doesn't 
exist, e.g. typo.  I end up unwittingly doing a popd backwards.

I just actually hacked this together.

    pd () {
    	[ $# -eq 1 ] && pushd "${1}"
    	[ $# -eq 0 ] && popd
    }

I should have expected (and did) that my function would be scrutinized. 
Which I'm cool with.  But even my buggy version demonstrates that 
function parameters do work, which is what the OP's question was about.  ;-)
