This C code may illustrate how "next", "break", "redo" behave
in Ruby:

/*****************************/
while (condition) {
  label_redo:

    goto label_next;        /* next */
    goto label_break;       /* break */
    goto label_redo;        /* redo */

    /* some code */

  label_next:

}

label_break:

/*****************************/
