extend looks good. but I don't understand where one can use it, apart from extending a function for different types.

In the Arc server, I moved creating the request object out of 'respond (http://awwx.ws/srv-misc), so that 'respond is now being passed the request object and does the usual Arc srv action to respond to a request: look to see if there is a defop etc. defined for the request path.

Now I can extend respond to implement my own ways of responding to requests: I can easily have my own way of choosing which action to take (I can have http://myserver.com/1234 display the "1234" item page, for example), or implement my own kinds of defop's.

I see it now. So type based dispatch is just one of the cases where it can be used. Thanks for the explanation. but why rntz says it's less efficient?
