Bug #20720
openprism incorrectly marks SuperNode as forwarding in some cases
Description
class A
def foo(*b, &block)
end
end
class B < A
def foo(...)
super()
puts "2"
end
end
results in:
./ruby --parser=prism -I../ruby/lib -I. -I.ext/x86_64-linux -I.ext/common -r./x86_64-linux-fake ../ruby/test.rb

../ruby/test.rb: ../ruby/test.rb:284: argument stack underflow (-1) (SyntaxError)
It should differentiate between forwarding nodes and non-ZSUPER Super nodes with no arguments.
