.I type t 

.sp
The type of the hashtable keys\&.

.I val equal 
: 
.B t -> t -> bool
.sp
The equality predicate used to compare keys\&.

.I val hash 
: 
.B int -> t -> int
.sp
A seeded hashing function on keys\&.  The first argument is
the seed\&.  It must be the case that if 
.B equal x y
is true,
then 
.B hash seed x = hash seed y
for any value of 
.B seed
\&.
A suitable choice for 
.B hash
is the function 
.B Hashtbl\&.seeded_hash
below\&.
