->> x: insert/dup copy [] [c: c + 1] 52
== []
->> head x
== [c: c + 1 c: c + 1 c: c + 1 c: c + 1 c: c + 1 c: c + 1 c: c + 1 c: c + 1
c: c + 1 c: c + 1 c: c + 1 c: c + 1 c: c + 1 c: c
+ 1 c...
->> c: 0
== 0
->> reduce head x
== [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27
28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44
45 4...
I hope it is self explanatory now (in fact - it is crazy! :-) "Insanely
great" :-)
