> if tempinbox is not None:

I used to do this, but was a bit concerned it would be parsed
as:

if (tempinbox) is (not None)

...but it actually seems to be parsing it as:

if not (tempinbox is None)

...as if there's a token "is not", similar to "!="
Maybe we can change this in Python 1.6 to "isn't" ;-)
