John,
I was looking at the validates method and I had a thought I'd bounce off
you. Instead of
just returning a hash of errors what about returning the record with the
errors hash in
the metadata? That way you just have the data and the errors in one
"object" similar
to an ActiveRecord model.

I think this should be fine for 99% of situations, but I think it's
also fair to say this is an unorthodox use of java.ext.dirs. I've
never really had a firm grip on the idiomatic use of Java's extension
mechanism, but I do know that they claim it is for well-established
extension/optional packag

I tidied up a couple of things:
Changed function name 'verify-direction' to 'new-direction' (it is more than
a simple verification)
Passed 'direction' and 'snake-head' to 'new-direction' to avoid accessing
global state from inside the function

Clojure revision 1193 introduces metadata handling for namespaces and
other Reference types. I was thinking this could be used to add
support for ns-level docstrings such as we currently have for vars.
Such support would allow programatic access to namespace
documentation.

sqrt(a/b) should always be equal to sqrt(a)/sqrt(b) since (a/b)^m =
a^m/b^m for b != 0. However, I'm unsure of whether it's the best
