    Thought I might be more specific.

    I have the following command (ABNF with implied whitespace at
    obvious places):

    cmdline = "tence" ["-h"] *("-i" dirlist) 1*("-r" file 1*(test))

    and this completion function:

    -------------------------
    #compdef tence

    local context line state
    typeset -A opt_args

    _arguments -s : \
        {-h,--help} \
        '*'{-i,--include-path}'=:include_path:->incpath' \
        '*'{-r,--run}'=:file:->testfile:*::class:->testclass'

    case $state in
    incpath)
        _dir_list && return 0
        ;;
    testfile)
        _files -g '*(.)' && return 0
        ;;
    testclass)
        # offer tests defined by this file for completion
        local -a tests
        tests=($(_call_program tests tence -C $words[1]))
        compadd "$@" -a tests && return 0
        ;;
    esac

    return 1
    -------------------------

    with "mycmd -r F a b c <CURSOR>" on the command line, completion
    should offer not only further tests (d e f), but "-r" as well.

    I don't want to pollute the interface with dummy arguments to halt
    the class optarg processing on, and also would love to defer as much
    as possible work to the standard functions.
    
    _arguments is already there, I don't want to write another parser.
