 | This Lua module is used on approximately 126,000 pages. To avoid major disruption and server load, any changes should be tested in the module's /sandbox or /testcases subpages, or in your own module sandbox. The tested changes can be added to this page in a single edit. Consider discussing changes on the talk page before implementing them. |
 | This module is subject to page protection. It is a highly visible module in use by a very large number of pages, or is substituted very frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it is protected from editing. |
 | Module:No globals is deprecated. Please see mw:Extension:Scribunto/Lua reference manual#Strict library instead. |
The functionality this module provides was added to Scribunto itself (see T209310) and should now be used as <syntaxhighlight lang="lua" inline="1">require('strict')</syntaxhighlight>.
