About Perl 5

Perl v5 is a high-level general purpose programming language invented by Larry Wall and first released in 1987. It is an eclectic interpreted, procedural, loosely typed language. Its popularity peaked with the rise of the World Wide Web, though it remains widely used in Quality Assurance, IT infrastructure automation, text processing, bioinformatics and web application development, just to name a few areas. It is highly flexible, but this flexibility can have a follow-on maintenance cost.

Perl also has:

  • minimal built-in object support, but interesting 3rd party OO
  • first class functions
  • closures
  • a powerful built-in regular expression engine
  • the Comprehensive Perl Archive Network (CPAN), a massive library of user-contributed modules

Every well-known Unix and Unix-style operating system ships with Perl included.

A tremendous learning opportunity to explore the depth of your own knowledge

Exercism is fantastic in learning new languages but that is not the extent of it. If you are a "more experienced" programmer you may have encountered impostor syndrome: the idea you don't really know what you think you know. Exercism lets you solve problems and put them in the space of open feedback which is a tremendous learning opportunity to explore the depth of your own knowledge. Even if you have been programming in a language for awhile it is worth checking into Exercism to see where you stand with current implementation practices.

Relaxed. Encouraging. Supportive.

I've written Perl 5 for quite a while now at various $WORK, and worked on quite a few FOSS projects with it as well. I'd love to help other people on learning Perl 5, as well as learn from them along the way.

Fun. Challenging. Interesting

My first adventure in coding was creating userscripts by trial and error (many errors...). Somewhere down the line I accidentally found myself employed in my first coding role as a Perl developer, after attempting pair programming in Haskell.
