* with the following modifications:
* - General pretty formatting (pretty to my taste at least.)
* - Naming style changed to standard C++ library requirements.
* - safe_execute does not feature a try-catch protection, so we can
* use this even if BOOST_NO_EXCEPTIONS is defined.
* - Added scope_guard_impl4 and obj_scope_guard_impl3, (Boost.MultiIndex
* needs them). A better design would provide guards for many more
* arguments through the Boost Preprocessor Library.
