The good news is, you don't have to type "use strict" anymore; it's the default if you opt to declare Perl 5.11 or higher as the minimum for your module or script.

People seem to hate typing "my" to declare a variable, but that's fine. I appreciate the number of times that's caught bugs for me, and I appreciate the clarity of scoping it allows for. I never really figured out scoping in Python, because you never declare variables. In Python, you could write:

   def foo():
      def reset():
         x = 0
      def inc():
         x += 1
      def print():
         print x

And it would compile, but not be what you mean. In Perl, you'd write:

   sub foo {
       my $reset = sub { my $x; $x = 0 }
       my $inc   = sub { my $x; $x++ }
       ...
   }

and know exactly what's going on because you had to explicitly declare $x. You can instantly tell that the Perl is broken. But the Python looks like it works (but doesn't). That, to me, is a big deal.

Of course, it doesn't actually matter because you're not supposed to program like that in Python. But if you chose to anyway, ...
