Here's a fairly straightforward example: https://github.com/python-trio/trio/blob/master/trio/_deprecate.py#L114-L140 (Intentionally doesn't include __dir__ because I didn't want deprecated attributes to show up in tab completion. For other use cases like lazy imports, you would implement __dir__ too.) Example usage: https://github.com/python-trio/trio/blob/master/trio/__init__.py#L66-L98 -n -- Nathaniel J.
