I wanted to give it a try rewriting this in C but since @contextmanager has a lot of magic I wanted to ask first whether this 1) is technically possible 2) is desirable.
It is definitely technologically possible. However, the C implementation will be quite complex, and will require a lot of time to review and later maintain. My question would be how critical is the performance of @contextmanager? I'd say that unless it's used in a tight loop it can't affect the performance too much.
