[New-bugs-announce] [issue3108] Implicit exception chaining (PEP 3134)

[Antoine Pitrou]

New submission from Antoine Pitrou <pitrou at free.fr>:

This patch implements implicit except chaining (__context__) as per PEP
3134, or not quite. The difference is that PyErr_Set* functions do set
the __context__ attribute, otherwise I think it would make an annoying
discrepancy between exceptions generated by Python modules and
exceptions generated by C modules (especially when some parts are
written in C and others in Python, e.g. the io library).

Unimplemented are the modifications in exception reporting.
