“Rebol is often described as scripting language.”
“It is actually much more than that. Rebol is also a
language-description notation (based on the Backus-Naur Form), a
CGI-handler, and a visual programming language. Rebol is an
object-oriented language with inheritance and polymorphism, if you
wish it to be. It is also a procedural and functional language, if
you prefer, or even your particular mix thereof.”
“In other words, Rebol is all of Perl, Python, C, C++, Lisp,
Scheme, and PHP3. It may not have all the functionality or power of
each of the aforementioned languages and scripts, but it certainly
contains their best concepts and features.“
“The book, Rebol: The Official Guide, is true to its title.”
