Very nice! I would change the :satisfies clause for underachievers so
that it does not create an ordering dependency.

The get-in that ataggart suggested is probably what you want but

Short answer: no, because Java has no sizeof operator.
You can use Java profiling tools to examine the memory usage of your

Since all of clojure's data structures are persistent (reusable), they

I'm not sure, but closures actually sound like the way to go here.
That would be the traditional functional-programming solution to this

If you use the M-x clojure-install command, this should get all the

The other way of looking at these issues is that this style of

You could embed Jetty in your application and it will just work. If
