Of course, I should have added that using a
"negative subscript" (-2) would also speed up this code.

It's just that the $ solution will not hurt the speed of
normal (positive) subscripts, the way that it appears
the negative subscript solution would. Nor will it
require additional subscripting code to be emitted by
the Translator. I'm sure that the vast majority of subscripts will
continue to be the normal (positive) ones that we allow today.
