You will get a firm "oh quite possibly" for that. :) | Some arguments against their use: | * Item 14 in Meyer's More Effective C++ | (the Session destructor example was enough to convince me.)

We are pretty strict about suppressing g++ warnings and errors but this may not get addressed to g++ 4.7 or whichever warns about it. All in all it seems more like a stylistical issue. Thanks for the heads-up.
