See > for example this part of the C++ standard: I am not, so the point is not relevant. To give you an idea of the kind of work I do using RAII, I use it to output the structure of a PDF file. The PDF specification requires a lot of meta information to be kept around and output later, and all data is embedded in objects with different layers of embedding, compression and encoding. Without RAII, the user must remember when to call each little function. Everything has a header and footer, most of the time multi-levels. It is easy to get wrong and the PDF tools are not friendly as far as error reporting goes. I can't possibly show you proprietary code. I believe I already know the possible alternative. I also know from experience that anything that can be automated must be, it's the only way to reduce the error rate while improving productivity. --- [ comp.std.c++ is moderated.
