I have a small problem with clojure-mode in your setup.
Since clojure-mode is autoloaded, it, and SLIME, aren't available
until I load a '.clj' file.
Starting SLIME, though, doesn't add the SLIME menu to the previously
loaded '.clj' buffer
(Newly loaded files get the menu, as they should).

My OO example from earlier deals with this case by completely removing any
need to manually derive tags. This is done by having CLJOS keep it's own
internal hierarchy (via make-hierarchy) rather than using the default one.
By modifying metadata on the vars holding structs created by defclass

Can't some elements of the problem be solved with some form of predicate

(including myself) have been playing around with Clojure and wouldn't mind
meeting a fellow Clojurian! We arrive on Sunday and are planning on checking
FOSDEM out.
We're also giving a developer workshop on ShiftSpace in Brussels on the 12th
so if you're around come check that out
t is pretty
much a direct translation of the Java version minus mutation, in the next
version I hope to incorporate some of the suggestions in reply to my earlier
post (FMM in particular).

This would be easy to add to Spinoza, if you want perhaps we could hash it
out and we can add it. Or you can forge out on your own, but I think it's
always fun to join forces.

Just to note, the above shows that protocols could have their own
inheritance chain. This is insanely powerful and could be implemented very
quickly.

Provide a dispatch fn that extracts the runtime tag.

Sure but as you mention
Is there anything in core or contrib for parsing arguments to a
function? Since Clojure fns don't support optional args or even keyword
args, is there a standard set of helpers functions to do this? I looked
around but I didn't see anything obvi
