One of the implementers may correct me, but I'm not sure if it is so
much heavier the *[ there is in some sence processing all the nodes
anyway even if it is hidden inside an XPath rather than explictly using
templates. 

If you do want something callable as an XPath function then alternatives
are 
position() or count() with the exact expression depending on
quite what your document structure is, but for instance 
foo{count(preceding::*)}
might do what you want (You could use a key to pre-compute all of them
to save re-calculating, perhaps)
