Bug #22020

Updated by Eregon (Benoit Daloze) 5 months ago

```ruby 
 begin 
   foo(1, 2, kw: :arg) { 42 } 
 rescue => e 
   pp RubyVM::AbstractSyntaxTree.of e.backtrace_locations[0] 
 end 
 ``` 

 ``` 
 $ ruby --parser=parse.y rubyvm_ast_node_id_loc.rb 
 (FCALL@2:2-2:21 :foo 
    (LIST@2:6-2:20 (INTEGER@2:6-2:7 1) (INTEGER@2:9-2:10 2) 
       (HASH@2:12-2:20 (LIST@2:12-2:20 (SYM@2:12-2:15 :kw) (SYM@2:16-2:20 :arg) nil)) nil)) 
 ``` 

 That covers `foo(1, 2, kw: :arg)` so all arguments except the block argument, which looks inconsistent. 

 I believe it should be: 
 ``` 
 $ ruby --parser=parse.y rubyvm_ast_node_id_loc.rb 
 (ITER@2:2-2:28 
    (FCALL@2:2-2:21 :foo 
       (LIST@2:6-2:20 (INTEGER@2:6-2:7 1) (INTEGER@2:9-2:10 2) 
          (HASH@2:12-2:20 (LIST@2:12-2:20 (SYM@2:12-2:15 :kw) (SYM@2:16-2:20 :arg) nil)) nil)) 
    (SCOPE@2:22-2:28 tbl: [] args: nil body: (INTEGER@2:24-2:26 42))) 
 ``` 
 which covers `foo(1, 2, kw: :arg) { 42 }`.
