First class is a technical term which means that all things
in the language are data, everything is a "first class
citizen". What this means in practice in that functions are
not elevated above other datatypes, scalar or otherwise. In
practice, it allows functions to take other functions as
arguments as well as return functions. The first class
abilities of REBOL help make it its own metalanguage. First
class capability enables and enhances functional
programming. All expressions can be uniformly handled.
this could be a REBOL expression:
f f f f
What could it evaluate to? Let's see, it could be:
"F of the F of the F of the F".
or it could be:
"F the F of the F and the F"
or
"F the F and the F of the F"
or
"F and F and F and F"
etc...
