There is always a degree of tradeoff between power and ease of use.  But 
whether or not you like the way the xpath() function now works hardly 
matters - we're not going to change the behaviour of an existing 
function except to fix a bug.

As I said upthread, I think we can easily provide some extra convenience 
functions which will do what you want. The only thing I was really 
arguing about was the function name for such a gadget.
