We have:

    def foo(**ignore_all_options)
    end

    foo(bar: 42) # => nil, OK
    method(:foo).parameters # => [[:keyrest, :ignore_all_options]], OK

But:

    def foo(**)
    end

    foo(bar: 42) # => ArgumentError: unknown keyword: bar, expected nil
    method(:foo).parameters # => [], expected [[:keyrest]]
