It also returns nil values as nil, to allow for distinctions between nil and false. The module also ...
Let's take a practical example. for this example, assume your user name is "Lua Developer". Let's say you want to test a bug-fix or enhancement to the String module. There are two reasons you can't do it directly: this module contains functions that are used by hundreds of templates, transcluded in millions of articles.
