If you are using it, what are you using it for? Do you use it purely as a personal toolset/language or are you using it in a broader sense (i.e. many others use it, or the result of it)

Just curious if anyone has used this language much? I find it very interesting and has some good potential.

REBOL has no built-in way to perform list comprehensions. However, REBOL has a powerful facility (known as parse) that can be used to create domain-specific languages (DSLs). I've used parse to create such a mini-DSL for list comprehensions. In order to interpret the expression, the block containing the comprehension is passed to a funct...
Note
This is not a REBOL-specific question. You can answer it in any language.
Background
The REBOL language supports the creation of domain-specific languages known as "dialects" in REBOL parlance. I've created such a dialect for list comprehensions, which aren't natively supported in REBOL.
A good cartesian product algorithm is nee...
Imagine the following REBOL code:
foo: context [bar: 3]
I now have a context foo in which 'bar is defined. How can I dynamically inject a new word into this context? Is it possible?
I've tried:
set/any in foo 'baz 3
But that doesn't work because the expression in foo 'baz fails because there is no word 'baz defined in the foo contex...

I'm working on a project that has to read and manipulate QuickTimes on Windows. Unfortunately, all the tutorials and sample code at the Apple site seem to be pretty much Mac specific.

parse/all "a b c" rule
is OK but if I change rule to just

parse/all "a b c" rule

I'm writing a tutorial on Rebol's Object persistence but I'm not sure if my way is the best
suppose %config.txt contains
a: 1
b: 2
We can then load it with
config: construct load %config.txt
To save it back to file I use this
save %config.txt (pick to-block mold config 3)
But I'm not sure this is the most elegant syntax to do ...
