[REBOL] Re: Is Rebol OO?

Hi Behrang, BS> According to the messages sent to the list I learned BS> that REBOL is not OO. But it doesn't look to be BS> procedural or something else too. Isn't it an instance BS> of a new yet to be named paradigm?? RT calls it a "messaging" language. My favorite definition is that it's "designed to facilitate the semantic exchange of information between people and machines." It's a symbolic language, like Forth; it's a functional language, like Lisp; it's accessible to mere mortals, like Logo. You can use it in many ways: imperative, functional, declarative. I've had a number of "AHA!" moments (many of them thanks to the good people on this list)in my time with REBOL, as I'm sure you will. Realizing that "code is data, and data is code" is important. After I got there, it took a while before someone said "everything is data until it's evaluated" and another light went on. Other things like words refer to values; they don't contain them are important distinctions too. Learning when to use COPY on series! values, and the really important "local variable" behavior (someone must have a boilerplate example on hand for that one :). The number of "gotcha's" in REBOL is rally low (IMO), but you do have to keep an open mind sometimes and think about why it works the way it does. There's nearly always a good reason. Happy REBOLing! -- Gregg
