SYNOPOSIS

9         use Moose::Autobox;
10
11         my $adder = sub { $_[0] + $_[1] };
12         my $add_2 = $adder->curry(2);
13
14         $add_2->(2); # returns 4
15
16         # create a recursive subroutine
17         # using the Y combinator
18         *factorial = sub {
19             my $f = shift;
20             sub {
21                 my $n = shift;
22                 return 1 if $n < 2;
23                 return $n * $f->($n - 1);
24             }
25         }->y;

27         factorial(10) # returns 3628800

DESCRIPTION

30       This is a role to describe operations on the Code type.
31

METHODS

33       curry (@values)
34       rcurry (@values)
35       conjoin (\&sub)
36       disjoin (\&sub)
37       compose (@subs)
38           This will take a list of @subs and compose them all into a single
39           subroutine where the output of one sub will be the input of
40           another.
41
42       y   This implements the Y combinator.
43
44       u   This implements the U combinator.
