Show me code example.
Something like his (untested):
local function close_values(t)
for _, val in pairs(t) do
local <toclose> tmp = val
end
end
local <toclose> array = setmetatable({}, {__close = close_values})
When 'array' goes out of scope close_values will be called, which will call __close on all the values in the array.
