Lambda way (according to the docs, I haven't tried it): std::for_each( foos.begin(), foos.end(), _1 = bind( constructor< shared_ptr<Foo> >(), new_ptr<Foo>() ) ); (probably leaks when new throws) Old school way: shared_ptr<Foo> createFoo() { return shared_ptr<Foo>( new Foo ); } std::generate( foos.begin(), foos.end(), createFoo );
