No, not that easily. 1) I deem the first exception more important than the
one raised by .close(), and 2) the user may anticipate or even control the
exception being raised, so raising a different one may miss a well-forged
except statement in user code.

I actually mixed up the way exception chaining works in Py3. It's right to
always raise the first exception in both Py2 and Py3, and attach the second
exception only in Py3. The Python code snippets I gave were correct, though.

No schedule yet. Could you file a bug report for now?
