Do we have a general policy here? I guess there are quite some places (e.g. std::make_unique) where "Args&&..." could be replaced by "auto&& ,.."

std::forward? 🤨

I think it makes sense here because we don't need names for the types in the pack, it's just a sink accepting anything. Anywhere we need a name for the parameter (or parameter pack) using auto isn't an improvement.

std::forward -> std::make_unique; sorry for the confusion

That still uses std::forward, so we'd have to say std::forward<decltype(args)>(args)... instead of std::forward<Args>(args)....

Ok. So, the rule is we're only using "auto" as a parameter type if we don't need names. Makes sense.
