The text of the PEP seems to implicitly assume that all sub-iterators
will be generators, so it is not clear on the above points.
On the contrary, this question is explicitly addressed in the PEP:

I should have read it more carefully.
If you want to block an inadvertent close() call, you need to either
wrap the object so it doesn't implement unwanted parts of the
generator API (which is the iterator protocol plus send(), throw() and
close()), or else you should continue to use simple iteration rather
than delegation.
What about the exception being suppressed?
That doesn't seem to be mentioned.
Cheers,
Mark.
