Comment (by joaquin):

 The problem with erasing by key rather than by iterator is that the former
 can throw (when calculating the hash value of the key, for instance),
 which Boost.Flyweight can't afford.

 Have you tried using
 [http://www.boost.org/libs/flyweight/doc/reference/factories.html#set_factory

 set_factory]? Insertion is probably slower but deletion does not have the
 problems you describe.
