You can do that while hash-consing your values, which has many other benefits than allowing physical comparison, as explained in this paper: http://www.lri.fr/~filliatr/ftp/publis/hash-consing2.pdf Ocaml code for hash-consing can be found on that page: http://www.lri.fr/~filliatr/software.en.html Hope this helps, -- Jean-Christophe _______________________________________________ Caml-list mailing list.
