[The replace semantics you describe are unfortunate for me: my unification algorithm keeps a hashtable of variable -> term bindings into which I have to incrementally subtitute while iterating through the table.

I was hoping to just modify the table in place .. ~2.5 times faster ..] -- John Max Skaller, mailto:skaller@ozemail.com.au snail:10/1 Toxteth Rd, Glebe, NSW 2037, Australia. voice:61-2-9660-0850 ------------------- To unsubscribe, mail caml-list-request@inria.fr Archives: http://caml.inria.fr Bug reports: http://caml.inria.fr/bin/caml-bugs FAQ: http://caml.inria.fr/FAQ/ Beginner's list: http://groups.yahoo.com/group/ocaml_beginners
