This is not a full review of the proposed Boost.Local library, I've reviewed only Local Exits and a potential merge with Boost.ScopeExit. I vote NOT to merge Local Exits with Boost.ScopeExit for the following reasons: - Local Exits feature gives two different interfaces ("variadic" and "sequencing"). In my opinion, it should only document C++0X interface and have a section called something like "What if I don't have a C++0X compliant compiler?" where it will explain an alternative interface for a transitional period. Some compilers already support enough C++0X features to let you develop a "perfect" interface. - Binding of variables should be modeled after lambda captures. This means no this_ and no void. I really like void and I'd added it if Lorenzo came up with the idea at the time when Boost.ScopeExit was still in development. - For the same reason, const bind& and bind& should be removed from the interface.
