OTOH, there might be a 'save' function to save the game, but since you forgot to put 'save' in your hash (or worse, you made a typo), the user can't save.

More likely though is that all the subs dealing with user commands are stored in a different module. And you can do something like:

    while (<>) {
        my ($verb, @args) = split;
        no strict 'refs';
        if (defined &{"Verbs::$verb"}) {"Verb::$verb" -> (@args)}
        else {print "No verb '$verb' implemented.\n"}
    }

Why one would even want to bother with a hash in between is beyond me.
