Targhan: + couple points..
REBOL/View is free for normal use.. for distributing rebol programs commecially there's need for some licensing (compiler etc).
REBOL deliveres a lot what some others promised. Same code been able unmodified to run on 30 (or so?) different systems with GUI features (7 different CPUs, and 11 OS:es) . And a lot more, if one does not need GUI moduels and uses it for scripts, Cgi etc... see
http://www.rebol.com/download.htmlIt's a bit strange for programming language but it has really good wordset for network connectivity. So some people love it some hate. It's matter of how well one gets into it. Good thing is, it's free DL so it's not too expesive to give it a run.
