    Parentheses of the form ( Disjunction ) serve both to group the components of the Disjunction pattern together and to save the result of the match.
    The result can be used either in a backreference (\ followed by a nonzero decimal number),
    referenced in a replace string,
    or returned as part of an array from the regular expression matching function
