This code gets everything except the 4th item at index 3.
(<<<3){i. 10
0 1 2 4 5 6 7 8 9
Why is '3' boxed three times thought?
Also interesting / puzzling (the trend is that more dimensions mean less
boxing is valid):
(<<<3){i.10 10
Vs
(<<3){i.10 10
... and
(<3){i. 10 10 10
... and
(???){i. 10 10 10 N.B. are we at the outer limits now?
thanks,
