True of course, but I have a couple of arrays with data that are maintained
outside the program code, in a configuration file. So either I'd have to add
the indices manually to those arrays (and if one array entry is removed,
renumber the remainder) or I must preprocess the arrays (adding the counter)
before sending them off to the template.
The work-arounds are easy but I'd like a clean solution.
