} noticed that if i do something like:

Use the `path' array instead of the PATH scalar, and use `typeset -U'.

typeset -U path
path=($path /dh/bin)

Recent versions of zsh, e.g. 3.1.9/4.0.x, also allow `typeset -U' of a
colon-separated scalar like PATH, but the above will work in most 3.0.x
versions as well.
