[REBOL] Re: Please help me to promote REBOL

Hi Tim,
thanks for the code sample! I will get into this soon.
By the way: it looks a bit similar to a DEFINE in a LET fence in SCHEME with lexical
scoping. Is that right?
Did you mean btw that I may place it as an example on my site?
Met vriendelijke groet / with kind regards,
Arie van Wingerden

That's a really pretty web site!

(reb rings anyone?)
----------------------------------
For those new to rebol(and for you gurus to critique if you so wish),
I'm including a subroutine that I use frequently.
One of rebol's distinctive features is the variety of ways
in which code can be evaluated. Coming from architectural
languages like ASM and C, and using more conventional scripting
languages like python, I had a hard time getting that
under my belt. Still working at it actually.
and the fact remains, rebol documentation doesn't really hammer
down the distinctions in evaluation as much as should be
done, IMHO.
Following the control flow of 'fetch might be enlightening
to someone new to rebol *and* it illustrates the usage
of (what I call) an 'anonymous' function

P.S. I hate pretty-print!

make object! [
default-value: none
set 'fetch func[ {safe data retrieval. Handles any value}
v /seed {set default value} /deep {If block, reduce} /local tmp][
either seed[default-value: v][
either value? v[
either word? v[
tmp: get v
either all[deep block? tmp][reduce tmp][tmp]
][v]][default-value]]]]
