I actually think this is one of C++'s nicer idioms. It can be annoying
having to create the cleanup class, but it turns out there are a small
number of common reusable cases (.e.g, unlocking mutexes, closing files,
freeing pointers). It is also nice that you do not have to create a new
scope in order to define additional cleanup objects, which would otherwise
make your code harder to read.
