This PEP is a concrete proposal for exception chaining, to follow
up on its mention here on Python-Dev last week as well as earlier
discussions in the past year or two.
http://www.python.org/peps/pep-0344.html
I've tried to summarize the applications for chaining mentioned in
these discussions, survey what's available in other languages, and
come up with a precise specification.
PEP 344 proposes three standard attributes on traceback objects:
__context__ for implicit chaining (an unexpected exception
occurred during 'except' or 'finally' processing)
__cause__ for explicit chaining (intentional translation or
augmenting of exceptions, set by "raise EXC from CAUSE")
__traceback__ to point to the traceback
Hope this is useful. I'd like your feedback. Thanks!
