I implemented persistent, array-mapped Patricia trees in C a while ago:

It should be relatively straight-forward to build some Objective-C classes
on top of that. (There's a reason the memory management routines are named

Hi,
Something like this?
(let [f assoc]
(first
(filter (fn [v] (identical? @v f))
(map second
(mapcat ns-publics (all-ns))
Or even this?

%)

You have reused a name already bound in the `protocols` namespace. You
cannot bind two things to the same var.
On the other hand, precisely because namespaces are not complected with
protocol dispatch, you can easily free the `get` identifier for your
purposes by doing exactly what you would do
Hi,
In principle, dispatch is orthogonal to namespacing. It is true that
traditional OO systems complect these two things, but there is no inherent
need to do so. Separating dispatch (i.e., methods) from namespacing is
simpler and more flexible.
This is especially useful when you have multip

That's probably true. Reference counting is a good fit for tree-

I punted on it. GNUstep already had GC support at the time, and it

IANAL, but if I understand the GPL correctly, it prohibits you from
distributing a GPL-covered programme that is based on Clojure, because
it would need to be linked to

I don't know, but I suspect it might be matter of aesthetics. In CL,

For the sake of balance, I _am_ actually concerned about the CPL

unneutral.

Certainly, something compatible with the GPL wouldn't have to be the
GPL itself.
(This doesn't mean I'd like to see Clojure's license changed. Just
wanted to clarify things.)

Personally, I'd define multimethods as the “interface“, in a single
