Please Check How Perl Saved the Human Genome Project to know how large a scale Perl reached that it is intertwining with Humanity, and also check BioPerl to see how a large library of many Perl modules are adopted as the primary front to facilitate Biological Sciences chores and errands using Object Oriented philosophy.
Update: let me add some buzz, BioPerl maybe large, but seemingly small snippets of Perl can do large things that can make a Perl programmer a Robin Hood to some and a fugitive to others, check Threat Level, isn't it strange that his name rhymes with Schwartz?.

About this first link, you may say that this is over a decade ago but knowing Perl stepped in means Perl is actively engaged -with dominance- there in the support and maintenance of many Biological Sciences IT interfaces and information management and is being as indispensable to a bioinformaticist as a lab coat to a doc is.
