MatchInfo.fetchNamed

Retrieves the text matching the capturing parentheses named @name.

If @name is a valid sub pattern name but it didn't match anything (e.g. sub pattern "X", matching "b" against "(?P<X>a)?b") then an empty string is returned.

The string is fetched from the string passed to the match function, so you cannot call this function after freeing the string.
