Your mileage may vary.

Anything wrong with the following?

[code rewritten using new stack_construct facility] It looks fine to me. Also, please ignore my previous statement about the relative merits of try{}catch(...){} wrt to RAII. The performance gain of the former shows only, it seems to me, when using scope guards. In your case, in which destruction *always* takes place, I doubt anything can beat what you've just written.
