Topics

Scope guards, aka scope_exit, scope_success, scope_fail and unique_resource. This could be in relation to Alexandrescu's book. Also what exactly is the library fundamentals v3?

Length

I think this would require a full length episode, but if you can compact it on a short episode this would be fine too.

Seems like this could have some overlap with #25 (throwing exceptions from destructors)
