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
