The ":" in the get-word ":face" prevents the Rebol interpreter from
doing an extra evaluation step; that is, the evaluation associated with
words referring to function! values.
For example, try this:
A: []
F: does [print "In F" 123]
insert tail A F
B: []
insert tail B :F
Here's one I prepared earlier:
>> a
== [123]
>> b
== [func [][print "In F" 123]]
Can you see the difference now?
