Here's another question:  is it possible to catch floating point
exceptions such as division by zero?  It seems like that might be another
way of dealing with this.  I thought catching SIGFPE would do it, but I
tried and I couldn't seem to get it triggered.  Is it possible to convert
floating point exceptions to ocaml exceptions?

&gt;&gt; 1- Fix polymorphic equality so that it behaves like IEEE equality on

&gt;&gt; 2- As J M Skaller proposed, change the behavior of polymorphic
&gt;&gt; equality
&gt;
&gt; Doesn't the polymorphic comparison have to be a total order?
