Perl’s function arguments no longer require you to shift or to access the @_ array. There are even proper argument signatures now. There’s also continuing improvements in putting a one true way to do objects into the core language, so you don’t have to bless a hash, use Moose, or Moo, or use Object::InsideOut (or any of a dozen other non-core modules).

All that old code still works, though.
