Sorry for my loose wording. Again, then:
Having a third, and even a fourth, argument need not
be difficult and would certainly be useful, especially
(in my direct experience) in teaching beginners tacit
programming.
At the risk of boring long-term readers of this forum,
my repeated suggestion has been for the use of [. and
]. to bring in operands just as [ and ] bring in
arguments. Then with &[. [.& &]. or ].& you would
effectively have third and fourth arguments. There
would be many other simplifications then made available
as well.
