This is a reference implementation of PEP XXX, which
makes writing "x[]" equivalent to writing "x[()]".

It passes the Python test suite, but currently doesn't
provide additional tests or documentation.

The attached diff doesn't include changes to
auto-generated files.

Attached is an improved patch, which does exactly the same
thing but with less code. It shows that, at least from the
implementation's point of view, an empty tuple for an empty
subscript list works like an n-tuple for an n-sized
subscript list.

You can also see it in http://python.pastebin.com/715221

Rejected per Guido's pronouncement on python-dev.
