[issue43002] Exception chaining accepts exception classes

[Ram Rachum]

Ram Rachum <ram at rachum.com> added the comment:

People barely know how to use the right form of this feature. Providing them with a wrong form that's confusingly similar to the right form and fails silently is an unfortunate choice. 

"Or just don't do anything. A `raise exception` inside an except block will be automatically chained with the current exception [...]"

With the wrong message, yes.
