Hi all, The recently discussed MSVC-specific trick, by Igor Chesnokov, has been added to the BOOST_TYPEOF submission. As a reminder, this implementation compiles much faster, and doesn't require type/template registration. This implementation covers VC6.5/7.0/7.1, but not VC8.0 (where the loophole seems to have been fixed). Please take it in the Boost sandbox file vault, http://boost-sandbox.sourceforge.net/vault/, typeof.zip. Regards, Arkadiy
