Good question. It will be released in a few days, and we basically expect that the behavior of the final compiler will closely match the behavior of the RC. I also know of an issue of Boost.Iterator with MSVC-10 (<http://lists.boost.org/Archives/boost/2010/03/163133.php>), but I will wait until the final release of MSVC-10 is available before I start to push on it.

One reason to start early with a non-stable compiler is that misbehavior in core libraries like utility/result_of or Boost.Iterator causes failures in dependent libraries, and these indirect failures can be difficult and time consuming to track down.
