shared_ptr<> can't be easily used in lambda expressions, because there is no operator->* defined. So, there are two problems in two different libraries: 1) operator->* needs to be added to Smart Pointers library. It can be easily done for data-members, but not for methods, since it includes return type deduction from template parameters. So there is another problem: 2) boost::function_traits<> from Type Traits library (result_type particulary) does not work for class methods.
