You can have as many marked sub-expressions as you want, and refer to them 
in the match_results structure once you have a match.  What you can't do at 
present is have a true back-reference say \12 in your expression.  This is 
basically a problem with the regex syntax, so if you know of a good syntax 
extension that's already in use then it would trivial to support this.
