    //     # Why not state the obvious? Just to be sure!
    //     - narrate 'You just used the /testcommand command!'
    //
    //     # You can utilize any arguments that come along with the command, too!
    //     # <context.args> returns a list of the arguments, run through the Denizen argument
    //     # interpreter. Using quotes will allow the use of multiple word arguments,
    //     # just like Denizen!
    //     # Just need what was typed after the command? Use <context.raw_args> for a String
    //     # Element containing the uninterpreted arguments.
    //     - define arg_size <context.args.size>

    //       - narrate "Here's a list of all the arguments<&co> <context.args.as_cslist>"
    //       }
    //
    //     # Commands won't be checked for <replaceable tags> So if you type /testcommand <player.name>
    //     # It won't be read as /testcommand mcmonkey
    //     # If you want tags to be parsed (read and translated), you can instead use '<context.parsed_args>'
