I'm not sure what you mean by 'make your classes new-style'.

According to 
http://www.python.org/doc/2.3.4/ref/specialnames.html, the 
__getitem__ method should be used, and the __getslice__ 
method is deprecated.

If you subclass the built-in list type, then the __getitem__ 
method is *not* called when subscripting with a slice.  
Instead, the __getslice__ method is called.  Try it out.

So I can't see any reasonable way to get around this bug.

You can try and modify the class C shown above, so that it 
behaves correctly.  I don't think you will be able to do it 
without putting in special "workaround" code to avoid this 
Python bug.

y = C([1, 2, 3])
>>> print y[-7:-5]         # should be [].
