summary:
New PEP 490: Chain exceptions at C level
+Python 3.5 introduces a new private ``_PyErr_ChainExceptions()`` function which
+is enough to chain manually exceptions.
It also was added in Python 3.4.3.
I meditar about adding _PyErr_ReplaceException() in 2.7 for simpler
backporting patches from 3.x.
+Functions like ``PyErr_SetString()`` don't chain automatically exceptions. To
+make usage of ``_PyErr_ChainExceptions()`` easier, new functions are added:
+
+* PyErr_SetStringChain(exc_type, message)
+* PyErr_FormatChaine(exc_type, format, ...)
Typo.
+* PyErr_SetNoneChain(exc_type)
+* PyErr_SetObjectChain(exc_type, exc_value)
I would first make these functions private, as _PyErr_ChainExceptions().
After proofing their usefulness in the stdlib, they can be made public.
