37
38       A hashing function on keys. It must be such that if two keys are  equal
39       according  to  equal , then they have identical hash values as computed
40       by hash .  Examples: suitable ( equal , hash ) pairs for arbitrary  key

43       -        ( (=) , MoreLabels.Hashtbl.HashedType.hash ) for comparing ob‐
44       jects by structure (provided objects do not contain floats)

46       -        ( (fun x y -> compare x y =  0)  ,  MoreLabels.Hashtbl.Hashed‐
47       Type.hash  )  for  comparing objects by structure and handling nan cor‐
48       rectly
49
50       -        ( (==) , MoreLabels.Hashtbl.HashedType.hash  )  for  comparing
51       objects by physical equality (e.g. for mutable or cyclic objects).
