Replace the single quotes with double quotes above and it'll work.  It
seems that you original intention was to eval the expanded string but
strings within single quotes are not expanded.  In zsh-3.0.0
$1=$2 worked as an assignemt but it was a bug and it does not work
anymore.

E.g. this should work:

	namedir () { eval $1=\$2 ; if [[ ! -d ~$1 ]]; then unset $1 ; fi }
