Superior!
Less tokens, less primitives and a lot faster and leaner.

Hello R.E..;

Given that the comparison machinery of  Less(-.) is not really needed, I 
submit the following::

   3(}.i.)7
3 4 5 6

Unfortunately it presents the same space usage problems:

    1000003 (}.i.)1000007  NB. makes two BIG lists and discards most of 
them.
