Hello. This won't be a proper review of the library, but more a point of view of an average Boost user. ScopeExit seems like a very nice utility, but, I don't think I could ever use it because of two things: 1. Dependence on boost.typeof. I would like the native typeof keyword, but, boost.typeof too much stresses compile type and a requirement of type registration is so unergonomic that makes boost.typeof a very nice and powerful demo, but not a useful utility for every day use. 2. Unusual syntax, both for me and someone who would later work on my code. Using preprocessor sequence and having BOOST_SCOPE_EXIT_END after {} braces looks so unnatural in C++. If, by any chance, my vote will be counted, I'll vote no for this utility until those two items are resolved. I understand maybe it's not possible to do so, but, I would rather not have it in Boost then.
