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
already have an idea how to do this.

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?
