- !ruby/struct:SM::Flow::P 
  body: Element Reference---If passed a single <tt>Fixnum</tt>, returns the code of the character at that position. If passed two <tt>Fixnum</tt> objects, returns a substring starting at the offset given by the first, and a length given by the second. If given a range, a substring containing characters at offsets given by the range is returned. In all three cases, if an offset is negative, it is counted from the end of <em>str</em>. Returns <tt>nil</tt> if the initial offset falls outside the string, the length is negative, or the beginning of the range is greater than the end.
- !ruby/struct:SM::Flow::P 
  body: If a <tt>Regexp</tt> is supplied, the matching portion of <em>str</em> is returned. If a numeric parameter follows the regular expression, that component of the <tt>MatchData</tt> is returned instead. If a <tt>String</tt> is given, that string is returned if it occurs in <em>str</em>. In both cases, <tt>nil</tt> is returned if there is no match.
