Ain't going to happen.  If you want that kind of thing without forking
your own version of Python, Numeric/numarray is the closest you'll get
(no special syntax, but lots of useful functions and 'ufuncs').

I'd guess you can subclass numarray's arrays and get this behaviour.
Or simply write your own sequence object and override __getitem__.

I'd guess it's highly unlikely ever to be part of the standard
sequence protocol, though.
