I think the barrier to adoption is the size of the Spirit library and
its dependencies. For example, I'd be afraid to write a small library
that forces my users to depend on Proto, MPL, and Fusion too. That,
IMO, is too much to ask.
People might not be aware though that Spirit is very modular. The
numeric parsing/generating utilities are in fact just a couple of
small *independent* header files. It might be a good idea to
fully decouple them from Spirit into, say, Boost.Utilities.
This is becoming more pertinent now that more people are needing
them. Indeed, parsing and generating numbers is not easy. Make
