Thanks!
It works as expected now. 
It was not obvious to me that you needed to capture in order for
regex_token_iterator to work, allthough it does now that you clarified.
There is no way to overload left or right parentheses :-)
Perhaps a note in the docs or another example will help other people not to
make the same mistake. 
Thanks again for your answer and xpressive!
