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
