[New-bugs-announce] [issue22387] Making tempfile.NamedTemporaryFile a class

New submission from Antony Lee:

Currently, tempfile.TemporaryFile and tempfile.NamedTemporaryFile are functions, not classes, despite what their names suggest, preventing subclassing.  It would arguably be not so easy to make TemporaryFile a class, as its return value is whatever "_io.open" returns, which can be of various types, but NamedTemporaryFile can trivially converted into a class by reusing the body of _TemporaryFileWrapper (which is not used elsewhere).
