Thanks Gordon for forwarding the Kevlin comments.
Looking forward a simple and power library making easier conversions ;-)
If taking this further, I would just find or write a library capable of glueing together function/functor overloads. The overloads would still be operator()(Source const&, type_tag<Target>) and there would be some convenience class which defines member function template<typename Target, typename Source> Target cast(Source const&); But of course I won't get around to it unless I find some other reason why I need such a thing! :-) Still hoping someone will chime in and say Phoenix (or Egg?) already does this. Jeff has suggested a plausible design using Eric's can_be_called in the other thread. Cheers, Gordon
