Loaders for objects, which load data (or some other object) into some variable, which can then be accessed as "foo or get_foo()", where the function get_foo sets the object to "foo" and then returns it.

Returns the name of the Wikipedia article for the script. `project` specifies the language and project to retrieve | |||
the article from, defaulting to {"enwiki"} for the English Wikipedia. Normally if specified it should be the project | |||
code for a specific-language Wikipedia e.g. "zhwiki" for the Chinese Wikipedia, but it can be any project, including | |||
non-Wikipedia ones. If the project is the English Wikipedia and the property {wikipedia_article} is present in the data | |||
module it will be used first. In all other cases, a sitelink will be generated from {:getWikidataItem} (if set). The | |||
resulting value (or lack of value) is cached so that subsequent calls are fast. If no value could be determined, and | |||
`noCategoryFallback` is {false}, {:getCategoryName} is used as fallback; otherwise, {nil} is returned. Note that if | |||
`noCategoryFallback` is {nil} or omitted, it defaults to {false} if the project is the English Wikipedia, otherwise | |||
to {true}. In other words, under normal circumstances, if the English Wikipedia article couldn't be retrieved, the | |||
return value will fall back to a link to the script's category, but this won't normally happen for any other project. | |||
