Infinite Number of Flags

[shellscape]

While educating myself on auto-complete, I was poking at npm and noticed that their autocomplete scripts allow for an infinite number of flags to be referenced by the completion mechanism, without regard to what position they're in. While the positioning that omelette provides is useful, removing that constraint would also be immensely useful. For reference, here is the script that results from running $ npm completion

###-begin-npm-completion-###
#
# npm command completion script
#
# Installation: npm completion >> ~/.bashrc  (or ~/.zshrc)
# Or, maybe: npm completion > /usr/local/etc/bash_completion.d/npm
#

if type complete &>/dev/null; then
  _npm_completion () {
    local words cword
    if type _get_comp_words_by_ref &>/dev/null; then
      _get_comp_words_by_ref -n = -n @ -n : -w words -i cword
    else
      cword="$COMP_CWORD"
      words=("${COMP_WORDS[@]}")
    fi

    local si="$IFS"
    IFS=$'\n' COMPREPLY=($(COMP_CWORD="$cword" \
                           COMP_LINE="$COMP_LINE" \
                           COMP_POINT="$COMP_POINT" \
                           npm completion -- "${words[@]}" \
                           2>/dev/null)) || return $?
    IFS="$si"
    if type __ltrim_colon_completions &>/dev/null; then
      __ltrim_colon_completions "${words[cword]}"
    fi
  }
  complete -o default -F _npm_completion npm
elif type compdef &>/dev/null; then
  _npm_completion() {
    local si=$IFS
    compadd -- $(COMP_CWORD=$((CURRENT-1)) \
                 COMP_LINE=$BUFFER \
                 COMP_POINT=0 \
                 npm completion -- "${words[@]}" \
                 2>/dev/null)
    IFS=$si
  }
  compdef _npm_completion npm
elif type compctl &>/dev/null; then
  _npm_completion () {
    local cword line point words si
    read -Ac words
    read -cn cword
    let cword-=1
    read -l line
    read -ln point
    si="$IFS"
    IFS=$'\n' reply=($(COMP_CWORD="$cword" \
                       COMP_LINE="$line" \
                       COMP_POINT="$point" \
                       npm completion -- "${words[@]}" \
                       2>/dev/null)) || return $?
    IFS="$si"
  }
  compctl -K _npm_completion npm
fi

Would it be possible to allow the same kind of "as many flags as you want in any position" functionality?

Very late comment, but for those who still have this problem I worked around it by using the supported "Global event" found here on the README.

Snippet:
complete.on('complete', (fragment, { reply }) => reply(["hello", "world"]));
