In order to see the difference, you have to change something in the "deep"
data:
>> a: [ 1 2 [ 3 [ 4 5 ] 6 ] 7 8 ]
== [1 2 [3 [4 5] 6] 7 8]
>> b: copy a
== [1 2 [3 [4 5] 6] 7 8]
>> c: copy/deep a
== [1 2 [3 [4 5] 6] 7 8]
>> change a/3 9
== [[4 5] 6]
>> a
== [1 2 [9 [4 5] 6] 7 8]
>> b
== [1 2 [9 [4 5] 6] 7 8]
>> c
== [1 2 [3 [4 5] 6] 7 8]
This shows that 'copy/deep did a true copy of the imbedded blocks, where
'copy did not.

Subject: [REBOL] copy versus copy/deep
As my example below shows, there does not appear to a difference in
handling nested blocks between copy and copy/deep
>> a: [ 1 2 [ 3 [ 4 5 ] 6 ] 7 8 ]
== [1 2 [3 [4 5] 6] 7 8]
>> b: copy a
== [1 2 [3 [4 5] 6] 7 8]
>> b
== [1 2 [3 [4 5] 6] 7 8]
>> c: copy/deep a
== [1 2 [3 [4 5] 6] 7 8]
>> c
== [1 2 [3 [4 5] 6] 7 8]
>> b
== [1 2 [3 [4 5] 6] 7 8]
>> a
== [1 2 [3 [4 5] 6] 7 8]
