&gt; However, there is one thing that particularly disturbs me about OCaml
&gt; - the way that it handles floating point values.  In OCaml a floating
&gt; point value is always 64 bit, and because only values that are always
&gt; the size of a machine word internally are not allocated, floating
&gt; point values in OCaml are ALWAYS allocated on the heap!!

"Often", but not "always".  Detailed explanations on float boxing are
available here:
