[REBOL] copy versus copy/deep Re:
From: joel:neely:fedex at: 28-Aug-2000 11:32
See what happens, after executing the code from your example, if you
modify a nested sub-block of a. That's the difference.
>> append a/3/2 99
== [4 5 99]
>> a
== [1 2 [3 [4 5 99] 6] 7 8]
>> b
== [1 2 [3 [4 5 99] 6] 7 8]
>> c
== [1 2 [3 [4 5] 6] 7 8]
