As far as "Microsoft bug" is conserned, my testing wasn't accurate. After I #include "boost/mpl/size.hpp", which I use, VC7 is fine and VC8 is fine with T() + U(). It still can't handle make<T>() + make<U>(), though...
Can you submit a small test case that uses make<>? This one is important and should get attention from the MS engineers.
I'll do once I figure out what's going on... Eric's suggestion moved me past the immediate problem, but now I am having another one, related to sizeof(...) not being recognized as a constant expression... A good news is that I probably know how to fix it by simplifying (removing some optimization), so that VC8 is able to handle this -- it works with my preliminary tests. The price will be decreased performance of BOOST_TYPEOF_TPL (but not BOOST_TYPEOF) in VC8 only, for simple types, but your example should be fixed once I do this. Until I find a better solution it probably makes sense to upload the patched version, so that we could move on with the review. I'll do it some time tomorrow if I don't find anything better until then. Regards, Arkadiy
