[issue23700] tempfile.NamedTemporaryFile can close too early if used as iterator

[R. David Murray]

R. David Murray added the comment:

There's actually an issue about exactly that broken-per-docs issue for io.  IMO if the goal of calling close is to close only things that are generator objects or pretending to be one, the method should have been named close_generator or something.
