While discussing https://bugs.python.org/issue32145, I noticed that ExitStack.callback *always* adds a wrapper function, even when the `args` and `kwds` parameters are both empty. For plain callbacks that aren't receiving any extra arguments, it would be better to skip adding the redundant wrapper function. |

I think I am missing something because the callbacks are always called with (exc_type, exc, tb) (check here https://github.com/python/cpython/blob/176baa326be4ec2dc70ca0c054b7e2ab7ca6a9cf/Lib/contextlib.py#L475) and therefore a wrapper that just drops these arguments and calls the original callback with no arguments is always needed, right? |

Ah, you're right, I wasn't thinking clearly when I filed this - the correct public API method to transfer existing exit stack entries to a new stack would be "ExitStack.push()". I'll make a note of that on the original issue. |
