ns-unmap-all

[blais]

Hi,
The following function has been a real _lifesaver_ lately in debugging
symbol collisions in (ns) directives when developing with SLIME in a
long-running VM:

(defn ns-unmap-all
"Unmap all the symbols (except 'ns' and 'in-ns')."
([] (ns-unmap-all *ns*))
([ns] (map #(ns-unmap ns %) (keys (ns-map ns)))))

May I kindly suggest the inclusion of something similar along with all
the other core namespace functions?
It's quite nice (IMHO: necessary) to be able to get back to a clean
environment when you face a collision error.
(I'm guessing may of you have something similar already defined in
your environments.)

cheers,

[Stuart Sierra]

This will help with collisions, but note that other namespaces may
still hold references to the values of the un-mapped Vars.

There's also "remove-ns" in core, which, when followed by "ns", will
have the same effect.

I've had this on my todo list for swank-clojure for a while now; would
love to see a patch that integrates it. Not sure it belongs in
clojure.core though.

shouldn't we rename remove-ns to ns-remove to keep it in line with the
other ns functions?

Yes.

And you should consider wrapping the call to map into (dorun) so that you're sure that once the function exits, all the ns-umap calls are done.

In fact you should use doseq. dorun is so ugly.
