Hmm, Playing with this stuff, I ran into that :

  (each c (annotate '(int cons) 3) (prn c))
  -> Error: "Function call on inappropriate object #3(tagged (int cons . nil) 3) (0)"
The problem is that each calls acons and alist, but they are defined in terms of (is (type x) 'cons) instead of (isa x 'cons). Once you redefine them, it works fine.

pg, do you still accept suggestions about the core functions ? Shouldn't acons and alist be defined with isa instead of is ? That would let us redefine them more easily. Btw, what do you think of all these discussions about types ?
