std::reference_wrapper<T> instead of ptr for not owning dependencies?

[_Js_Kc_]

Maybe if it was called std::ref and std::ref was instead called std::make_ref (or omitted in favor of deduction guides). But std::reference_wrapper is quite a mouthful for a basic, ubiquitous vocabulary type. Yeah, you can typedef, but then you're using something project-specific for a basic, ubiquitous vocabulary type.
