The behaviour of the "async with" statement in CPython does not match the description of it in PEP492, nor the language documentation. The implementation uses a try/except/finally block, while the PEP and documentation describe the behaviour using a try/except/else block. The PEP and documentation should be updated to reflect the true intention of "async with". |

The specific issue is that early exits from an "async with" statement are actually defined the same way they for synchronous with statements: exiting early via return, break, or continue, is the same as reaching the end of the try block. However, that's not what the documentation currently says: it describes "async with" in terms of try/except/else, which isn't correct. |
