Description

Currently, Kernel#warn is basically the same as $stderr.puts. With the new Warning.warn support in ruby 2.4, it makes sense for Kernel#warn to call Warning.warn, otherwise you will not be able to use Warning.warn to filter/process warning messages generated by Kernel#warn.

The Kernel#warn API is different than the Warning.warn API, the attached patch tries to get similar behavior, but there are probably corner cases where the behavior is different.
