Subject: [Caml-list] Map.iter unspecified order of visiting -- reason?
To cite the manual of Map:
val iter : (key -> 'a -> unit) -> 'a t -> unit
 iter f m applies f to all bindings in map m. f receives the key as first 
argument, and the associated value as second argument. The order in which the 
bindings are passed to f is unspecified. 
Any special reason to do so?  I mean the source code actually implements
ordered visiting and it is indeed one of the great advantages of using a Map
instead of a Hashtbl (the other it being sideeffect free).  So why not 
document / require it to visit the keys in an well defined order with regard
to the ordering function?
