Ah yes, I forgot about *that* case, which just goes to show that what Martin says is right :-) Rich. -- Richard Jones Red Hat Fri, 20 Nov 2009 09:28:49 GMT Martin Jambon http://tech.groups.yahoo.com/group/ocaml_beginners/message/11571 http://tech.groups.yahoo.com/group/ocaml_beginners/message/11571 ... Beginners should note however that the Obj module should not be used in regular programs and that float arrays use a special internal representation which Thu, 19 Nov 2009 23:01:45 GMT Richard Jones http://tech.groups.yahoo.com/group/ocaml_beginners/message/11570 http://tech.groups.yahoo.com/group/ocaml_beginners/message/11570 ... Well, it largely depends on how you define the word "nicer" but in the current implementation tuples are basically the same as Arrays (even for tuples of Thu, 19 Nov 2009 15:19:27 GMT Jon Harrop http://tech.groups.yahoo.com/group/ocaml_beginners/message/11569 http://tech.groups.yahoo.com/group/ocaml_beginners/message/11569 ...

Yes. That's a bit nightmarish because you just turned your elegant tree into a non-trivial graph, significantly increasing the size of a node (therefore Wed, 18 Nov 2009 16:15:54 GMT Mac Mason http://tech.groups.yahoo.com/group/ocaml_beginners/message/11564 http://tech.groups.yahoo.com/group/ocaml_beginners/message/11564 ...
