/* Until some official version of the ScopeGuard idiom makes it into Boost,
 * we locally define our own. This is a merely reformated version of
 * ScopeGuard.h as defined in:
 *   Alexandrescu, A., Marginean, P.:"Generic<Programming>: Change the Way You
 *     Write Exception-Safe Code - Forever", C/C++ Users Jornal, Dec 2000,
 *     http://www.drdobbs.com/184403758
 * with the following modifications:
 *   - General pretty formatting (pretty to my taste at least.)
 *   - Naming style changed to standard C++ library requirements.
 *   - 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.
 *   - Added scope_guard_impl_base::touch (see below.)
 *   - Removed RefHolder and ByRef, whose functionality is provided
 *     already by Boost.Ref.
 *   - Removed static make_guard's and make_obj_guard's, so that the code
 *     will work even if BOOST_NO_MEMBER_TEMPLATES is defined. This forces
 *     us to move some private ctors to public, though.
 *
 * NB: CodeWarrior Pro 8 seems to have problems looking up safe_execute
 * without an explicit qualification.
 * 
 * We also define the following variants of the idiom:
 * 
 *   - make_guard_if_c<bool>( ... )
 *   - make_guard_if<IntegralConstant>( ... )
 *   - make_obj_guard_if_c<bool>( ... )
 *   - make_obj_guard_if<IntegralConstant>( ... )
 * which may be used with a compile-time constant to yield
 * a "null_guard" if the boolean compile-time parameter is false,
 * or conversely, the guard is only constructed if the constant is true.
 * This is useful to avoid extra tagging, because the returned
 * null_guard can be optimzed comlpetely away by the compiler.
