Moose::Autobox::Code - the Code role

version 0.16

  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

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

"curry (@values)"
"rcurry (@values)"
"conjoin (\&sub)"
"disjoin (\&sub)"
"compose (@subs)"
This will take a list of @subs and compose them all into a single subroutine where the output of one sub will be the input of another.
