That is better although I would prefer to pass in a token (assuming that 
is where index is declared). Then it would be an implementation detail 
that "index" is used to get the location.

Another option would be to turn it around:

sturct/class Location
{
     Location find/locate (Token token);
}

I see. For convenience there could be properties defined that just 
forwards the call to some other function.
