...(or use tr1 type traits)? Certainly adding a dependency on Boost is a big change and deserves lots of scrutiny. But there is a ton of good stuff in there that is really useful for compiler work. In my own work I've made use of tuples, BGL, MPL (very limited), bind (also in tr1), optional, io_state_savers, iterators, static_assert, and will probably soon be using multi_index to improve algorithmic complexity. A smaller step would be to accept tr1 things. I'm not making a big push for Boost or tr1, just raising the question to start a discussion about the long-term direction of the project...
