So, *for* is a wart, too, then. ;-)
It, too, can only be used in a few specific places.
But, together with an object’s Range
attribute, we get an unequivocal statement that

The range does not need to be programmed by 
hand; that would be verbose. I like to reserve
‘Last to one-off specification of subranges.
