[Boost-users] [Phoenix] Can we use boost::phoenix::function<Impl const&>?

Greetings, The intuitive way to make a PFO having state is letting boost::phoenix::function hold the impl's reference, however, the following does not work. struct Impl { ...defines a functor having state... }; Impl impl; boost::phoenix::function<Impl const&> f(impl); f(...lazy call...); // should return an actor here, but not compiles Is this intended behavior?
