I've seen those from RT say that REBOL words are not variables, (as apposed to calling variables "words" just to be different), and the following perhaps helps to explain why...
>> blk: [a few words]
== [a few words]
>> blk/1
== a
>> type? blk/1
== word! What is variable about 'a 'few and 'words in such an example? Okay, they can be set, unset and so on, but that's not what people think variable means in relation to programming. Thinking of them as the datatypes they are is probably the best mental view to have of them after you're past the beginner stage. -- Carl Read
