+####DICT\_SET\_DEF2(name, key\_type, key\_oplist)
+
+Define the set 'dict\_##name##\_t' and its associated methods as "static inline" functions.
+A set is a specialized version of a dictionary with no value.
+
+It shall be done once per type and per compilation unit.
+It also define the iterator dict\_it\_##name##\_t and its associated methods as "static inline" functions.
+
+The oplist is expected to have the following operators (INIT, INIT\_SET, SET, CLEAR, HASH and EQUAL), otherwise default operators are used.
+If there is no given oplist, the default operators are also used. The created methods will use the operators to init, set and clear the contained object.

+Interface is subjected to minor change.
