Are semicolons required?  Let's try ...

---- Do this in the global namespace
list = {}
function reminder(self,item) list[self] = item end
debug.setmetatable(0, {__call = reminder})
-- The following is OK
(1) "Butter" 
(2) "Eggs" 
-- This too
(3) "Tea"; (4) "Coffee"
-- But this gives an error
(5) "Whisky" (6) "Beer"
-- As does this
(7) "Brandy" --[[
--]] (8) "Gin"
