This is the place to test lua codes, as Lua modules cannot exist as subpages in the User: namespace.
Please only test your own lua codes. If you want to test other modules, please fork them. And, please name your experimental modules in the following format to help keep things tidy:
Module:Sandbox/Your User Name/Module name
-- This is a placeholder. -- Please name your module as Module:Test/Your User Name/Module name to keep things tidy.
