Unless I'm missing something, this has nothing to do with asynchronous code. The delete is just synchronous code running, same as if we called a function/closure right there.

This is just about syntax sugar hiding function calls.

I'm assuming you're referring to the Python finaliser example? If so, there's no syntax sugar hiding function calls to finalisers: you can verify that by running the code on PyPy, where the point at which the finaliser is called is different. Indeed, for this short-running program, the most likely outcome is that PyPy won't call the finaliser before the program completes!
