There are few things to correct/clean up:

(1) The "C API" paragraph contains incorrect information:
  - the sentence "The PyErr_Set* calls for setting exceptions will not set the
'__context__' attribute on exceptions" is wrong. The __context__ attribute is
actually set in PyErr_SetObject.
  - the sentence "PyErr_NormalizeException will always set the 'traceback'
attribute to its 'tb' argument and the '__context__' and '__cause__' attributes
to None" is wrong. The __context__ and __cause__ attributes are set to NULL in
BaseException_new
  - there are no functions PyErr_SetContext/PyErr_SetCause, but
PyException_SetContext/PyException_SetCause.

(2) "Open Issue: yield" has been fixed with the lexical exception handlers patch
(see test case:
http://hg.pitrou.net/public/py3k/py3k/file/184db4b87529/Lib/test/test_raise.py#l100
)

(3) "Open Issue: Garbage Collection" has been resolved as part of PEP 3110 (see
"semantic changes" in the latter)

(4) "Open Issue: Limiting Exception Types" has been solved since exception types
must all derive from BaseException

Antoine.
