[Boost-users] [bind][lambda] overriding return value

Hi, Is it possible to override/generate a return value? I want to connect a signal that has a bool return value to a method that has a void return type, generating always a true return. class X { public: void f(); }; boost::signal< bool () > sgn; X x; sgn.connect( boost::bind( &X::f, &x ) ); // error, signal has bool return, method doesn't David
