Comment:
This isn't quite as clear as it looks. Slicing a normal `QuerySet` will
sometimes return a list as well; it depends upon whether the results have
already been retrieved from the database or not.
''Probably'' the solution here is a documentation one, but it's worth
thinking about what else might be possible. Always returning a `QuerySet`,
though, is, from memory, a little fiddly to organise efficiently and
always correctly.
