A possible way, as implemented in my example, is to use a multi-valued
map (std::multimap) to store keys so that for each key value you get a
set of objects.

The second step is to store corresponding signature in the object "as
the object type" so that you can check for correct signature with a
dynamic_cast<> of stored objects against the dispatch request.

Anyhow "simple_factory.hpp" code is much clear then the above explanation... ;-)
