+ * Simple default implementation of a hash set. The stored items are
+ * zero-terminated strings. The hash table does not manage the
+ * allocation of the strings, like it doesn't manage any stored items.
+ * However, it items are created with, say, strndup, a destructor can be
+ * provided to free each item when clearing the table. The remove
+ * operation also returns the removed item so it can be deallocated by
+ * callee.
+ *
+ * In general, the key and the item are different, but here they are the
+ * same. Normally the key would be referenced by the item.
