Hi Gisle
Nice solution. I would like to add a small clarification. When you use
insert/dup it places 5 references to the one instance of the series into the
new block.
>> a: head insert/dup copy [] "series" 5
== ["series" "series" "series" "series" "series"]
>> a/2/1: #"a" ;change first character of second series in block
== "aeries"
>> a
== ["aeries" "aeries" "aeries" "aeries" "aeries"] ;They are all changed!
BTW adding copy before "series" will not change the behavior because
insert/dup only evaluates it once.
If we want independent copies of the series in the new block, we need to use
a different approach.
>> b: copy [] loop 5 [append b copy "series"]
== ["series" "series" "series" "series" "series"]
>> b/2/1: #"a"
== "aeries"
>> b
== ["series" "aeries" "series" "series" "series"] ;only second series
changed
Now they are independent.
Which one you want depends on what you want to do with the block.
Cheers
