This module causes an error if any nil [[global variable|global]] is read or if any global is written to, with the exception of <var>arg</var>. To use, add <syntaxhighlight lang="lua" inline>require('Module:No globals')</syntaxhighlight> to the top of the module using it. The <var>arg</var> variable is excluded because it is necessary for Scribunto's [[mw:Extension:Scribunto/Lua reference manual#require|require]] function to work properly. (See the Scribunto source code [[phab:diffusion/ELUA/browse/master/includes/engines/LuaCommon/lualib/package.lua;1fad4da13706f4dbdd0477a834675b9d09757bf6|here]].)
