the real world is mostly complicated.

the best module all over the world looks like

local …
local function ...
return { func1, ……. }

sometimes it might be used like (reduced of course)

return require ‘module’

called from C code. and, yes, C programmers very strong and paranoidal, they check how many results returned from Lua code to minimize stupid unpredictable errors. I’m pretty sure it’s bad idea to ignore extra results, we mustn't to ignore errors.
