Or (real Python):def fn(): for i in range(10000): with open(f"file{i}.txt", "w") as f: f.write("Some text") How would you write this in your RAII style - without leaving 10,000 file descriptors open until the end of the function?
IIUC, if the OP's proposal were accepted, the __del__ method would be called as soon as the *value*'s reference count went to zero. That means this wouldn't leave 10,000 files open, since each open() would assign a new file object to f, which would make the previous file object's ref count be zero, and it would be closed.
