Again, you're arguing preference. A fruitless discussion

sreich: It might be partly preference, but I would argue that you should have a good reason to do anything that deviates from the standard way of doing things, be it better readability, better performance, less typing or something else, but I see none of that in your `finish`-function.

Which really does the same thing but behind the scenes

Though I think I would prefer to create more specific extension functions like use, for classes that require that

It has some similarity, but `use` actually adds value by hiding that hideous try...finally construct. `use` is more readable compared to the standard way, and it's quicker to type.
