[REBOL] Propagating Refinements

From: greggirwin:starband at: 10-Sep-2001 11:58

Is it possible to, in a simple way, propagate refinements to other functions? For example, I want my stack/add routine to support an /only refinement, which it then passes on to insert (example code below). Can you do it without an either clause, or getting more involved as Ladislav's refined function does? Thanks! --Gregg stack: make object! [ _data: make block! 25 ; Use list! instead of block!? clear: does [_data: make block! 25] count: does [return length? _data] empty?: does [return count = 0] item: does [if not empty? [return last _data]] remove: does [if not empty? [system/words/remove back tail _data]] add: func [value /only] [ either only [ insert/only tail _data :value ][ insert tail _data :value ] ] contains?: func [value /only] [ either only [ return found? find/only _data value ][ return found? find _data value ] ] ]
