Agreed. Boost.Phoenix will have placeholders named _1, _2, etc. With 
some thought, we might be able to define these placeholders such that 
they can be shared across Bind, Phoenix, Spirit (Qi/Karma/Lex), 
xpressive, etc., and squish this placeholder issue for good. Making them 
Proto terminals would be a no-brainer except for the portability issues 
to ancient compilers. But now that we're breaking back-compat, it might 
be time to reconsider the Bind placeholder portability hacks.

Anyway, sign me up for helping out with this one. I'd like to see a 
unified set of placeholders.
