Thanks bob. That makes sense now.
(<0;1;<<1) { i. 2 2 3
2
(<0;1;<<1) { i. 2 2 3
3 5
(<0;1;(0 2)) { i. 2 2 3
3 4 5
(<0;1;(0 2)) { i. 2 2 3
3 5
(<0;1;a:) { i. 2 2 3
(nothing returned)
(<0;a:;1) { i. 2 2 3
1 4
... the only strange thing I guess is that
(<0;1;a:) { i. 2 2 3
is not equivilent to
(<0;1) { i. 2 2 3
thanks,
-Steven
