By abstracting away the countless ways a function can handle cleanups, you are providing a single, uniform interface that anyone can implement. This concept is akin to the usage of `.then`, where you agree upon an interface that allows people to execute asynchronous work. The syntax sugar of async/await relies on the existence of a `then` key, demonstrating similar concept.

this is a great explanation, thanks!

In the context of the parent question then it's the consistent standard syntax that makes things easier to read - something that indeed is impossible to see with an isolated example that, if anything, may look less clear than the syntax you're used to.
