Method calls are incorrectly parsed

[divarvel]

using the v5 branch,

check if $a.length();
check if $a.contains("a");

is parsed as

    (source_file
      (authorizer_element
        (check
          (rule_body
            (expression
              (methods
                (expression
                  (term
                    (variable)))
                (nname))))))
      (authorizer_element
        (check
          (rule_body
            (expression
              (methods
                (expression
                  (term
                    (variable)))
                (nname)
                (ERROR
                  (string))))))))

it seems that the method calls are correctly parsed as long as they don’t have arguments.

I have tried with defining $.method_argument to be just $.expression (or even $.term) and got the same issue
