Anyway, isn't boost::placeholders too presumptuous? It's not like any of the other libraries that use placeholders will be using these placholders. Unless they are! That would be sweet.
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. -- Eric Niebler BoostPro Computing http://www.boostpro.com
