type of the table

clear tab removes all entries from the table tab.

hashcons tab k returns either k, adding it to the table tab as a side effect, or if k is already in the table then it returns the hashed object corresponding to that entry.

• raises Failure

  if number of objects with the same hash reaches system limit of array size

iter f tab applies f to every live hashed object in the table tab.

fold f tab x0 folds f across every live hashed object in the table tab, starting with value x0

count tab returns a count of how many live objects are in tab. This can decrease whenever the GC runs, even during execution, so consider the returned value as an upper-bound.
