This is probably getting to be more standards-related than
boost-related, but...  Assuming it isn't proprietary information, it
would be useful if you could say a little bit about what your
intrinsic looks like.  As you may know, the core people, especially
EDG, would like to see those sorts of intrinsics standardized. 
Everyone is going to have to implement some kind of interface that
makes type traits implementable, and the EDG people figure that
everyone might as well all implement the same thing.
