Question

I have been hearing a lot about this “Modern Perl.” What is it?

One of the things I heard was the new open syntax:

open my $FH, '<', $filename

and not

open FH, "<$filename";

What else is in Modern Perl?

Answer 1

To add some specifics to deinst’s overview, Modern Perl:

• uses Perl 5.10’s new features, like switch statements (given / when) and say
• follows good Perl programming practices, like use strict and use warnings
• may use the Modern::Perl CPAN module to streamline all of this
• uses Moose for writing high-level OO code
