Over the years I have used 20+ languages, starting with CobolC and Watfor, and now python is my daily driver. Rebol is by far the most enjoyable language I have ever used, very similar to Smalltalk and Lisp. More productive than any other system out there and a very small footprint. The language is unbelievably versatile as you can overload any word and create your own mezzanine functions super quickly. The drawback are that you can really messup if you are not careful. Another thing is that compiling is out of the question as the self modifying code possibilities of this language make it truly dynamic. Carl did a marvellous job on this language. The design is impeccable. If you like messaging then this is THE language.
