That does make sense-- and, it's a good question. So far (and I'm new to 
using this library) for my own purposes, I would say that the convienence 
of inline notation would be nice. On the other hand, the most complicated 
parse so far in my current project benefits from being able to build up a 
grammar in small parts, and indeed involves a few copies. Hmm.

Done, ticket 1990. By the way, I'm using xpressive in a current project 
and am having tremendous /fun/ working with it so far! You'll be pleased 
(if unsuprised :>) to know that it's processing hundreds of thousands of 
records from real-world data with nary a hitch, and I might add performing 
extremely well.

Thanks!
