  * 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.
