[issue25782] CPython hangs on error __context__ set to the error itself

[Yury Selivanov]

Yury Selivanov added the comment:

> Setting it to NULL is one option -- silently ignoring the assignment
(leaving whatever was there) might also be good? In 90% of the cases it
would be the same thing right? 

But leaving the old __context__ there will completely mask the bug...

And as for pure python code -- do you agree we better raise a TypeError if a cycle is about to be introduced?
