Issue #19281 has been updated by jeremyevans0 (Jeremy Evans).
YARP parses all of these successfully:
```ruby
YARP.parse("p (1;2),(3),(4)").success?
# => true
YARP.parse("p (;),(),()").success?
# => true
YARP.parse("a.b (1;2),(3),(4)").success?
# => true
YARP.parse("a.b (;),(),()").success?
# => true
```

These are syntax error
~~~ruby
p (1;2),(3),(4)
p (;),(),()
a.b (1;2),(3),(4)
a.b (;),(),()
~~~
I expect it to be syntax ok because the code below is syntax ok.
~~~ruby
p (1),(2;3),(4;5)
p (),(;),(;)
a.b (1),(2;3),(4;5)
a.b (),(;),(;)
~~~
It will be easy to traverse sexp if the sexp of first argument is same as others
~~~ruby
Ripper.sexp "p (),(),()"
# =>
[:program,
[[:command,
[:@ident, "p", [1, 0]],
[:args_add_block,
[[:paren, false], # [:paren, [[:void_stmt]]]
[:paren, [[:void_stmt]]],
[:paren, [[:void_stmt]]]],
false]]]]
Ripper.sexp "p (1),(2),(3)"
# =>
[:program,
[[:command,
[:@ident, "p", [1, 0]],
[:args_add_block,
[[:paren, [:@int, "1", [1, 3]]], # [:paren, [[:@int, "1", [1, 3]]]]
[:paren, [[:@int, "2", [1, 7]]]],
[:paren, [[:@int, "3", [1, 11]]]]],
false]]]]
