zsh: stop backward-kill-word on directory delimiter

Question

In zsh, how can I set up the line editor such that backward-kill-word stops on a directory separator? Currently in my bash setup, if I type

cd ~/devel/sandbox
<

For recent versions of zsh, you can simply add:

autoload -U select-word-style
select-word-style bash

to your zshrc as described in zshcontrib(1).
