Changes
fix bug where explicitly deleted args were still appearing when iterated over with pairs or ipairs - code courtesy of User:Jackmcbarn
-- into one table using the specified iterator. If a value is already
-- present it is not overwritten; tables listed earlier have precedence.
-- We are also memoizing nil values, but those values which can beoverwritten if they -- overwrittenare 's' (soft).
