I've been playing with writing a Zork-style engine, to scrape the rust off my C and possibly learn LISP. The basic structure is to define a bunch of locations, objects, and commands. The commands are a mapping between a word (read in from the commandline) and a funcp. So far, so good. Except, the function signature I'm using is getting more and more complex, to account for all the possible cases. Yet, each function is only using 2 or 3 of the currently 7 parameters being passed in. And, it's limiting me in terms of providing location-specific functions.

I started thinking about how I'd go about implementing this in Perl. 

$locations{road}{actions}{north} = sub {
    $_[LOCATION] = $locations{woods};
};
$locations{road}{actions}{woods} = $locations{road}{actions}{north};

It's the lack of anonymous functions in C that's pissing me off. Whoever implemented them in Perl ... THANK YOU!

I shouldn't have to say this, but any code, unless otherwise stated, is untested
