Here's my "zleread" function again.  Insert some commands to fiddle with
the completion context just before the call to "vared" and you can get it
to complete any way you like.

--- 8< --- cut here --- 8< ---
emulate -L zsh
local input opt ropt n=0
ropt=()
while getopts :AEe opt
do
    case $opt in
    [?]) read $*; return $?;;
    +*) break;;
    *) ropt=($ropt -$opt); ((++n));
    esac
done
if [[ -t 0 ]]
then
    shift $n
    vared -hp "${${(M)1%%\?*}#\?}" input
    print -r $input | read $ropt ${1%%\?*} $*[2,-1]
    return $?
fi
read $*
