Scribunto Testing Area
Lua modules cannot exist as subpages in the User: namespace. Therefore, this sandbox is my experimental module.
Special:PrefixIndex/Module:Sandbox/Unready lists modules in this area.

Helper function that populates the argument list
There may be a mix of named and unnamed parameters
