But if we ever turn it into a single token (which we just may for Py3k) don't complain if your code breaks.

It's something of an arbitrary choice, but to me it just seems that the dot and bracket should be separare tokens, perhaps because I would be thinking of the [x] as a special kind of argument to the dot operator, rather than there being a funny new operator called ".[".

Yes, that's how I was thinking of it. But it's all moot now.
