I do not believe that adding ranges eliminates the need to care about old things. It's also impossible that no one will try il.cbegin() and get a compile error.

After adding methods to std::initializer_list, there is no need to overload free function templates.

Can't you just use the `ranges::*` functions that do all of those
without having to add a dozen member functions?

Also, what "does not need to provide overloads for std::initializer_list."?
