Issue: NTH-VALUE (Version 3)

[Kent M Pitman <KMP@STONY-BROOK.SCRC.Symbolics.COM>]

My notes from Fairfax meeting...

Cleanup meeting:

 Thought to be ready to vote.

X3J13 meeting:

 JonL: Trivial, gratuitous.

 RWK: Not trivial -- allows index computation. Hard to do this
      in a portable, efficient way.

 Allard: Says he has an NTH-VALUE macro for a portable system that he
	 uses (which exploits the computed index feature) and that it's
	 a gross kludge on Lucid in order to make it efficient.

 KMP: Also, in principle, an implementation could make this more
      efficient than the alternatives.
