[issue18861] Problems with recursive automatic exception chaining

[Nick Coghlan]

Nick Coghlan added the comment:

Nothing is lost either way, it just isn't displayed by default.

While I can see the appeal of treating an "outer" context differently from an "inner" one, I don't see any way for the exception context suppression machinery to tell the difference.

The traceback *display* machinery might be able to figure it out by looking at the traceback details, but such a search could be quite expensive.
