Subject: [Caml-list] NaN-safe min and max
Olivier Andrieu proposed the following code for doing a safe min/max. 
Does anyone have any thoughts about this code snippet, and whether it is
or is not a safe use of Obj.magic?

 let min a b =
    let o = Obj.repr a in
    if Obj.is_block o && Obj.tag o = Obj.double_tag
    then Obj.magic (fmin (Obj.magic a) (Obj.magic b))
    else Pervasives.min a b
