Backport #7922: Keyword arguments bug with unnamed rest

• Status: Closed
• Assignee: nagachika (Tomoyuki Chikanaga)

[marcandre (Marc-Andre Lafortune)]

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]]
