PATH is no array, so "typeset -a" feels wrong.
PATH and path are already tied by default, no?

As for "typeset -U", that's useful to have, but I can definitely see
that one may want to e.g. temporarily add a directory path at the start
of PATH/path and then remove it again without disturbing the old values
of the variables.
