Rather than having the wrapper forward arguments to the constructor (adding unnecessary moves in some cases even if done using perfect forwarding; and just not looking good to my taste), I'd do this:
template <typename T>[[nodiscard]] T &unmove(T &&value){ return static_cast<T &>(value);}Foo(std::vector<Base *>{&unmove(Derived1(1)), &unmove(Derived2("name"))});Such unmove() function lets you take addresses of temporaries, and is useful in some other cases too (e.g. the last usecase I remember is passing rvalues to std::make_format_args()).
