Hi, list,
From de console:
>> system/version
== 2.5.55.3.1
>> data
== [10 20 30]
>> n: 2
== 2
>> data/2
== 20
>> data/:n
== 20
>> data/(n)
== 20
>> data/(n: 3)
== 30

Hi, list,
About http://www.rebol.net/blog/carl.html#section-5
Here's Carl's exemple:
data: [10 20 30]
n: 3
This shorthand for accessing elements in blocks is added to rebol version 2.5.55:
data/:n: 150
But then: is it absolutely clear that this should mean
poke data n 150
Couldn't it just as well mean:
n: 150
pick data n
i.e. with the form
:n:
which should be evaluated first, :n or n: ?
This might be a dumb question, but I don't see that this is all that clear. Elucidate
me!
