Module:No globals
Lua error: Internal error: The interpreter has terminated with signal "11". Lua error: Internal error: The interpreter has terminated with signal "11".
This module causes an error if any nil global is read or if any global is written to, with the exception of arg. To use, add require('Module:No globals') to the top of the module using it. The arg variable is excluded because it is necessary for Scribunto's require function to work properly. (See the Scribunto source code here.)
