more advanced. My class is called invoke_on_destruct and multiple
of these scope-guards can be concatenated. So if you have multiple
data struc- tures which are changed you can revert all changes with
multiple individual scope-guards.
After you changed everything you do sth. like a commit by disabling
the last scope-guard. The enabled state is propagated on destruction
to the depending scope-guards so you only have to disable the last
and all depening scope-guards are disabled also.

It actually does remind me of the original scope guard in a sense.

What's the "original" scope guard ?
The only semi-official version is experimental::scope_exit.

I guess Chris means ScopeGuard by Petru Marginean and Andrei Alexandrescu:
