Here's one...

When evaluating whether a variable is None, don't compare it like this:

	if x == None:

instead, use:

	if x:

or:

	if not x:

The encourages a polymorphic approach.  If you must compare to None, use the
identify operator rather than equality:

	if x is None:

or:

	if x is not None:

// mark
