I wouldn't worry too much about your reputation. Your posts are top
notch, and you obviously know the language better than 90% of most
clojure users. Have confidence and laugh if you think someone is
disparaging: actions speak far louder than words.

Thank you.

That function is already written for you.
user= (def x (atom (with-meta [] {:foo 1})))
#'user/x
user= (meta @x)
{:foo 1}
user= (swap! x vary-meta assoc :bar 2)
[]
user= (meta @x)
{:bar 2, :foo 1}

See my reply to Ken. I recommend against writing swap-meta! in your
own code, except maybe as a shorthand for (swap! foo vary-meta);
certainly don't implement it from the ground up when the language
already gives you the function you want.

I'm a bit confused. It just looks like a normal function call.
(my-defmulti foo type)
(my-defmethod foo String [x] (str A String: x))
(foo Hello, World!)
So it just looks like an ordinary function. Extracting the multi-call

You can change the metadata on the object held by the atom (if that

One thing a bit annoying is if you want to alter the metadata in an
incremental way. To do that atomically
I am currently giving some lectures about Clojure to a group of
students. One of the Lisp features I promote to them is the ability to
write language in the language itself. So during the lecture when I
talked about multimethods one student asked if one could write own
multimethods implementation

Hi,
I suppose you are Unlogic from IRC. I don't whether you saw it, but I posted
some rough sketch: http://paste.pocoo.org/show/303462/
It just introduces the function binding, no other global objects are
introduced. The methods are stored in a map in an atom in the metadata of the

Making the thing work with (name args ...) is not too too difficult.
You'd have to have defmethod output both a def of an atom like above,
but with a gensym for a name, and a defn

Thanks for your response! Your example is very useful, though I wanted
to implement the multimethods without that multi-call layer, so it
will look just like an ordinary function. Thanks to Ken Wesson I

Oh, that's my fault, I tried with-meta function on the atom and it
wouldn't work. Still, after I defined an atom with some metadata in
it, how can I change it thereafter?
