This could led to a potential problem in code like this:
if some_condition:
query = MyTable.select(...)
else:
query = None
if query:
...
There is a subtle bug if self.count() returns 0. Currently people are
accustomed that SelectResults instances are always evaluated to True in a
boolean context.
I don't know, though, how often people write code like that.
