[REBOL] Re: IDIOMS: setting multiple words

From: greggirwin:mindspring at: 9-Oct-2003 15:10

Hi Sunanda, Sac> If you are going to use set, you could use a shorter method: Sac> set [foo bar baz] copy [] Sac> Another method you will see around is: Sac> foo: bar: baz: copy [] You have to be watch, though, for the distinction between setting each word to refer to its *own* copy of [] and setting them all to refer to the *same* copy of []. Inlining set-word!s is very handy, and safe, for non-series values, but I don't use it very often for series values. Sac> I've very occasionally had to extend a function that returned a single value Sac> to return more than one value... Yes, another idiom worth discussing. :) -- Gregg
