Hi everyone, A while back I had a conversation with some folks over on python-list. I was having issues implementing error handling of `AttributeError`s using `__getattr__`.
My problem is that it is currently impossible for a `__getattr__` in Python to know which method raised the `AttributeError` that was caught by `__getattr__` if there are nested methods. For example, we cannot tell the difference between `A.x` not existing (which would raise an AttributeError) and some attribute inside `A.x` not existing (which also raises an AttributeError). This is evident from the stack trace that gets printed to screen, but `__getattr__` doesn't get that stack trace. I propose that the error that triggers an `AttributeError` should get passed to `__getattr__` (if `__getattr__` exists of course). Then, when handling errors, users could dig into the problematic error if they so desire. What do you think? Best, Jason
