Wikipedia:Articles for deletion/Extensibility pattern

This page is almost word for word the same as this page from the Perl Design Patterns Book. It has been flagged as a how-to article and for not meeting Wikipedia's standards since 2009. --Pleasantville (talk) 16:32, 10 November 2015 (UTC)

• Redirect to extensibility. A quick search does not turn up any sources that corroborate this article's treatment of several well-known software extensibility technologies (covered in other articles) as a single software design pattern, so the article is a how-to guide masquerading as an encyclopedic article by the addition of a novel lede.
