Yes. One of the uses is when you are wrapping some sort of OS resource.
I've got a scope class which I use for file access;
stops you accidentally leaving the file open & locked.
I also use scope classes for storing intermediate results in complex
algorithms when I want deterministic collection. Use scope classes
and it all gets cleaned up when the algorithm finishes.
