I'm starting to think that we instead need a way to let them easily say "This resource, the one I just created or have otherwise gained access to? Link its management to the lifecycle of the currently running function or frame, so it gets cleaned up when it finishes running".
But how would it help with a partial iteration over generators with a "with" statement inside? def it(): with open(file) as f: for line in f: yield line Nathaniel proposal addresses this by fixing "for" statements, so that the outer loop that iterates over "it" would close the generator once the iteration is stopped. With your proposal you want to attach the opened file to the frame, but you'd need to attach it to the frame of *caller* of "it", right?
