[Python-ideas] Boolean value of file object?

Just an off-the-wall thought.

Is there any reason a file object's boolean value shouldn't be false
once it's been closed? This would allow replacing "if f and f.closed:" (to
make sure you have a file and it's open) with just "if f:". Is there
some use case where you want to verify that an object is a file
object instead of None (or another false value), and don't care if
it's closed?

My own thought is that this is a case where status quo wins, but
thought someone else might think the idea has more merit.
