I'm don't sure to understanding you at all. (maybe my sentence is
meaningless ?) 

So, do you think it's difficult to add this argument to read builtin
function ?

hmm, i think i understand differences between tag completion and
command completion

hmm ok, i understand now. So, in this case, it's possible to change
the function which called by _default for only one command using
zstyle ?

i'm very sorry to ask and ask again about style, but i want to
understand all.

sure, in fact i have :

% vi .zshrc
source .zsh/rc/functions.rc

fpath=($HOME/.zsh/functions $fpath)

% vi .zsh/rc/functions.rc

upgrade () {
    if [ -z $1 ] ; then
        sudo apt-get update
        sudo apt-get -u upgrade
        echo "sudo apt-get update" | ssh $1
        # ask before the upgrade
        local dummy
        echo "sudo apt-get --no-act upgrade" | ssh $1
        echo -n "Process the upgrade ?"
        read -q dummy
        if [[ $dummy == "y" ]] ; then
            echo "sudo apt-get -u upgrade --yes"

% vi .zsh/functions/_upgrade

#compdef upgrade

_arguments '*:hostname:_hosts'

% zcompile _upgrade

source .zshrc

upgrade <tab>

_upgrade <tab>

Thank you very much for your help, and sorry for the disturb.
(btw sorry for the post to zsh-workers instead of users)
