It would be nice to have an index variable in an FOR loop.

Example:

«FOR item:list INDEX index»
  «index.index0» // a counter starting at 0
  «index.index1» // a counter starting at 1
  «index.isFirst» // true for the first item in the list
  «index.isLast» // true for the last item in the list
«ENDFOR»

I assume there would also be something like «index.value» to retrieve the index of the current item in the iterable.

That would be either #getIndexZeroBased or #getIndexOneBased / #index0 / #index1

OK. I didn't quite understand the "a counter starting at 0" comment at first.
