I was thinking about the Eric IDE, which somehow manages to complete
values which are only returned by __getitem__ but are not in __dict__
(don't ask me how it does that).  However, __dict__ lookup still works
right in Eric regardless of __getitem__, so it seems that my proposal
would break nothing indeed.  I still admit that it might be confusing,
so maybe another new method (e.g. getItem() or getPath()) would be a
better choice.

I don't see potential trouble, unless you are using __dict__ keys to
build expressions for 'eval' or 'exec', which could be avoided by the
use of __getitem__.
