I'm trying to write a class that implements __getitem__(self, k),

Currently, I'm getting exceptions when I use string keys:

TypeError: sequence index must be integer

not allow non-int keys, and I assume that if I subclassed dict the reverse
type clash would occur.  

So, is there a way to "override" __getitem__ to accept both types of
