[REBOL] IDIOMS: setting multiple words
From: greggirwin::mindspring::com at: 9-Oct-2003 13:08
Hi All,
I had a thought as I was tinkering with different REBOL constructs, to
see which one I liked best, for a particular bit of functionality.
Sometimes, as you know, a very REBOLish idiom can make all the
difference in the world.
Here's the idea; you pose a scenario and people can post different
approaches they might use to handle it. It's not a contest for the
smallest solution, but rather to show different *ways* things can be
done.
;----------------------------------------------------------------
Scenario:
You have a number of words that you want initialized to "copy []" or
some other value. Do you do it like this?
foo: copy []
bar: copy []
baz: copy []
Or like this?
foreach word [foo bar baz][set word copy []]
Or something else.
Do you use a different approach for more or less words?
Do you do things differently if you're setting words in a object?
Do you do something different based on the initial value?
Is there anything else you take into consideration when you do this
kind of thing?
Thanks for playing!
