Hi, When working with view of boost::fusion I feel something frustrated because of the limited set of possible constructors. Indeed, apart from copy constructor, views usually only provide constructors taken l-value reference on sequence as input. I would like to extend the constructors set of views with some new ones which would also accept r-value references on view as input. This would allow some fancy combination at construction time as for example: vector <https://www.boost.org/doc/libs/1_77_0/libs/fusion/doc/html/fusion/container/vector.html><bool> v0(true);vector <https://www.boost.org/doc/libs/1_77_0/libs/fusion/doc/html/fusion/container/vector.html><int, char> v1(3, 'x');vector <https://www.boost.org/doc/libs/1_77_0/libs/fusion/doc/html/fusion/container/vector.html><std::string, int> v2("hello", 123); using view1 = joint_view< vector <https://www.boost.org/doc/libs/1_77_0/libs/fusion/doc/html/fusion/container/vector.html><int, char> , vector <https://www.boost.org/doc/libs/1_77_0/libs/fusion/doc/html/fusion/container/vector.html><std::string, int>>;using view = joint_view< vector <https://www.boost.org/doc/libs/1_77_0/libs/fusion/doc/html/fusion/container/vector.html><bool> , view1>; view aview = view(v0, view1(v1, v2));std::cout << aview << std::endl; I would be glad to contribute to the boost library by updating the boost::fusion views with some new constructors bu I'm not familiar with development in boost. What would be the next step to give a chance to my proposal to integrate boost ? Best regards, Herve
