I've been uploading the style-guide and the _arguments documentation
to my brain, and improved versions are on the way.  _arguments is
great!  However a few things perplex me:

- Why can't you have multiple MESSAGE:ACTION pairs with the
  *:MESSAGE:ACTION form?  I'm having to resort to using an auxiliary
  function, e.g.:

_perldoc {
    _arguments -s \
        '-h:help:' \
        '(-q)-f:Perl built-in function:_perl_builtin_funcs' \
        '(-f)-q:Perl FAQ keyword:' \
        '*:Perl pod pages:_perl_pods'
}

_perl_pods {
    local nm="$compstate[nmatches]"

   _perl_modules
   _perl_basepods
   _path_files -J "Perl modules and .pods" -/ -g '*.(pod|pm)'

    [[ nm -ne compstate[nmatches] ]]
}


- Is it possible to do something like (-foo)*:MESSAGE:ACTION, i.e.
  specifying completion for normal args only if -foo hasn't been
  specified?

<rofl>  I hadn't thought of that :-D
