Knowing that this option only accepts one value and after a few tests,
it seems that 'eval' is the right solution, . My function now looks like

  local stow_dir
  local -a stow_pkg_list

  eval set -A stow_dir $1
  [[ -n $stow_dir ]] && stow_pkg_list=( $stow_dir/*(-/N:t) )

  if [[ ${#stow_pkg_list} -gt 0 ]]; then
    _values -C "packages from $stow_dir" ${stow_pkg_list[@]}
    _message "no packages found in $stow_dir"

and the completion of parameters such as'$HOME' or'~/' works well !

I pushed my modifications on github. Thank you for the answers :-)
