Moose::Autobox::Code(3)

NAME
Moose::Autobox::Code - the Code role

SYNOPOSIS
  use Moose::Autobox;

  my $adder = sub { $_[0] + $_[1] };
  my $add_2 = $adder->curry(2);

  $add_2->(2); # returns 4

  # create a recursive subroutine
  # using the Y combinator
  *factorial = sub {
      my $f = shift;
      sub {
          my $n = shift;
          return 1 if $n < 2;
          return $n * $f->($n - 1);
      }
  }->y;

  factorial(10) # returns 3628800
