This module causes an error if any nil global is read or if any global is written to, with the exception of arg, and temporarily, name. To use, add
require('Module:No globals')
to the top of the module using it. The name variable is excluded because of a bug in MediaWiki (and will no longer be excluded effective May 1, 2014), and the arg variable is excluded because it is necessary for Scribunto's require function to work properly. (See the Scribunto source code here.)
