First of all, I'm strongly *against* the idea of :var.

However, I think a syntax that would work with no ambiguities, and not look too bad, would be:

    .var

e.g.

    sublist = lst[.var]

I would also be strongly against this suggestion - it simply deals with the problems I see with the current suggestion. It has its own problems, including (but not limited to) not being very obvious.
