package dune

Hashtable with a simple polymorphic type, but without the polymorphic equality.

This module re-wraps the hashtable implementation provided by Hashtbl.Make under a different interface: we just have a single type ('k, 'v) t, similar to a polymorphic hashtable.

This means that if you want a hash table generic over the type of keys, you don't have to put your type inside a functor.

Unlike the polymorphich hashtable (('k, 'v) Hashtbl.t), this does not use polymorphic hash and polymorphic equality, so this module does respect abstraction boundaries.
