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? Andrew J Martin Attendance Officer Speaking in tongues and performing miracles, in a culinary fashion.
