My inclination is that these two really don't matter all that much. They are

Hmmm, what would this involve? I know that we would need to implement an
operator() that supports currying and an operator that supports the Lambda
stuff. I suspect that a careful reading of the fullN class templates would
answer all of my questions, but I haven't gotten there yet.
I could see having a macro like "BOOST_FUNCTION_FCPP_SUPPORT" (possibly
defined by the FC++ headers before including boost/function.hpp, for

This would make me happy. I like FC++, but am (and have been---I think we've
discussed this before) a little concerned about the fact that we're
introducing a lot of nearly-redundant bits into Boost.
