Suggestion: Perl topic

[adrianfusco]

Maybe we can add some questions related with Perl (Perl, Cpan, DBIx, Mojolicious). It's still used in some projects even in big corporations. What do you think?

Some examples:

• Perl
  • What is Perl?
  • Perl data types.
  • Perl operators.
  • What is a Perl subroutine? Different ways to call a Perl subroutine.
  • Lexical and dynamic scoping. Purpose of the local and my operator.
  • Perl referencing and dereferencing.
  • Perl filehandle.
  • Perl regex.
  • Perl system calls and open3.
  • Perl modules. Difference between .pl and .pm extensions.
• Perl OOP
  • How can you define a Perl class?
  • What is a package?
  • What is the purpose of the bless function?
  • Perl Inheritance and SUPER
  • Method overriding
• CPAN
  • What is CPAN?
  • How to install modules with CPAN?

Perfect.

I did a pull request. I've added new questions with answers. I'll add the missing answers and some exercises.

I’ll try to add more questions and exercises asap.
