Re: Composing grammars

Great. I'll have a look at X3. I have two questions:
* How can I do the same grammar composition if the grammars
constructor takes an iterator as a parameter (for position tracking in
error handling).

* Would the X3 version compile on older boost versions 1.54 and 1.58?

Thanks!
