I still haven't implemented in a Forth of mine, but meanwhile I had this
simple idea as an alternative, for do-loop structures that are factored
in its own definition:

	: don't  ( n1 n2 -- | n1 n2 )
	  2dup = if  2drop unnest unnest then  ;

	: list  ( n1 n2 -- )
	  don't do  i .  loop  ;

I like the name `don't`, but I accept suggestions.
