I got an idea to take care of remaining 0.001% case.

have require set package.loaded.mod to false before it were fully loaded.
(it were currently set to some userdata anyway)

if package.loaded.mod == false then
  -- loading from require, but not yet finish ...
else
  -- standalone program
end

so, even if lua had mod.lua "require" by default, above
can test for mod.lua running as stand-alone program
