  New Revision: 51905

  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=51905

  Log:
    parse.y: simplify ripper_id2sym
    
    * parse.y (ripper_id2sym): remove unnecessary comparison as
      rb_ispunct has stricter condition, and cast explicitly to
      suppress warnings.

  Modified files:
    trunk/parse.y
