That does make it even more concise !

That said, I'm not sure how I feel about the enter/exit context being implicit behind this; as in, it reduces the amount of code, but I can feel like reading it back feels unintuitive.

Mind, it's not implicit! It's extracted into the @contextmanager function.

I respect that you phrase it as unintuitive, since intuition is learned. Indeed, to (very) many, the extracted form of the code sandwich is intuitive. You can observe the movement from explicit sandwiches to extracted in many languages (e.g. Scope.Exit, using in C#).

The power it brings is that the developer cannot possibly forget to cleanup, so the reader doesn't have to wonder whether they did. Assuming code is read 10 times more than it is written, inner peace will be your part after growing this intuition.

Indeed. I guess it's something I just have to get used to - can be regarded as analogous to the with keyword which, unless you've learned and used it properly, can look oddly incomplete.
