I didn't know that. I was only targeting C++03/C++11.

This should work with C++11:

template void with(T &&t, F &&fn) { fn(std::forward<T>(t)); }

with(make_foo(), [](foo &&f) { // do things with foo. }); // foo is destroyed.

Don't think I can help w/r/t C++03 though, the lack of lambdas is a killer.

One thing this method doesn't do is automatically determine if the scope exit prematurely.
