Bug #20720

Updated by luke-gru (Luke Gruber) 3 months ago

```ruby 
 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

 ``` 

 It should differentiate between forwarding ZSUPER type nodes and non-ZSUPER Super super nodes with no arguments. in this case.
