Your example does compile on VC8 beta -- thanks a lot. Now I'll try to aply it to typeof...
I believe I have substantially simplified the implementation of typeof and fixed the vc8 compatibility problems. See the enclosed typeof_impl.hpp I am a little concerned about the implementation. When I saw the complexity of what the BOOST_TYPEOF macro expanded into, I was a bit shocked. Aside from what I addressed, the fact that the expression gets repeated 100 times was really surprising to me -- it seems to me that asking the compiler to evaluate the type of the expression over and over could get to be quite expensive. The simplification I've made results in the expression being repeated "only" 50 times. Is it possible to do better? Also, on a stylistic note, the paucity of whitespace in namespace boost{namespace type_of{ seems a bit draconian (yes, I'm exercising my vocabulary today ;->). -- Dave Abrahams Boost Consulting www.boost-consulting.com
