.I type t 

.sp
The type of the hashtable keys\&.

.sp
The equality predicate used to compare keys\&.

.I val seeded_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 
.ft B
equal x y
.ft R
is true,
then 
.ft B
seeded_hash seed x = seeded_hash seed y
.ft R
for any value of
.ft B
seed
.ft R
\&.  A suitable choice for 
.ft B
seeded_hash
.ft R
is the function
.ft B
Hashtbl\&.seeded_hash
.ft R
below\&.
