To supply a real life use case for what's described in the above 
paragraph,  I've looked at the doc for raw as expressed in the xml
generated from:

https://github.com/boostorg/spirit/tree/develop/doc/x3

That contains:

  raw[a]

    boost::iterator_range<I>

    Presents the transduction of a as an iterator range

 From this I infer that an interator_range<I> is produced
where I is the Iterator to the parsers.

But how do I use this.  Grep'ing for raw shows:

so, a brief look at that code still didn't clear things up; so,
Please, Maarten, could you post the code where you make use
of raw so I wouldn't have to further guess how to do it?

-hopefully,
Larry
