Instance Method Details

#def_private_delegators(target, *private_delegates) ⇒ Object

Since Ruby 2.4, Forwardable will print a warning when calling a method that is private on a delegate, and in the future it could be an error: https://bugs.ruby-lang.org/issues/12782#note-3

That's why we revert to a custom implementation for delegating one private method to another.
