There are literally thousands of perl tutorials on the web and dozens of books available. I was curious about what method(s) you either are using to learn perl or have already employed.
Reading a book (e.g. Learning Perl? Programming Perl? Beginning /Mastering Perl for Bioinformatics?) and typing code snippets and/or assigned problems at the end of each chapter? Did/Does your school offer a formal perl course? Reading online tutorials?
