IIRC DO..LOOPs had been a hack for computers in the 60s.
A rather ugly hack, born out of necessity, slow and
often cumbersome to use. That it still persists in Forth
half a century later speaks for Forth's progressiveness.

Testing FOR NEXT on my DTC system showed 15% speed increase over
DO LOOP.  Putting 5 NOOPs (executes forth's address interpreter)
in the innermost loop brought it down to 6%.  Not worth it IMO.
