I could go either way on $p:whatever-we-call-it or p:whatever-we-call-it().

When this first came up, Alex suggested that it was easier in most
libraries to add a variable than it was to add a function.

If this position indicator is only available in p:matching-documents,
then I think it can be either. If we decide to make it available in
more places (I'm not yet convinced we should, personally), then I'd
start to think that a function makes more sense.

That'd be fine with me.
