[REBOL] best means of passing refinements from main to helper function? Re:(3)
From: jelinem1:nationwide at: 18-Sep-2000 8:35
But then this (the example below) explicitly lists the refinements in the
function body. I think the "ultimate" solution would process an arbitray
list, as with a loop. It is fairly short though :) and IS a step up from
'if statements, esp for more than 2 refinements.

Howdy, Michael:
The following approach is exactly elegant, but it gets the
job done and it's fairly short. I think it's kind of cute.
