            $item % 3 ? !0 : !1, $item
        },
        tturn => [ qw/ echo SAME / ],
        fturn => [ qw/ bravo NEXT / ]
    }

World of a difference.
Furthermore, if you dare, take a look at
F<t/process/quadratic.t> and F<t/process/sort.t>.
But better don't, those are horrible.

Now, illustration what I<$namespace> configuration parameter opens.

Classics:

    my $bb = Acme::FSM->connect(
        { },
        alpha => {
            switch => sub {
                shift % 42, ''
            }
        }
    );

Illustrations below are heavily stripped for brevity
(Perlwise and B<A::F>wise).

Separate namespace:

    package Secret::Namespace;

    sub bravo_sn {
        shift;
        shift % 42, ''
    }

    package Regular::Namespace;
    use Acme::FSM;

    my $bb = Acme::FSM->connect(
        { namespace => 'Secret::Namespace' },
        alpha => {
            switch => 'bravo_sn'
        }
    );

Separate class:

    package Secret::Class;

    sub new { bless { }, shift }
    sub bravo_sc {
        shift;
        shift % 42, ''
    }

    package Regular::Class;
    use Secret::Class;
    use Acme::FSM;
    
    my $not_bb = Secret::Class->new;
    my $bb = Acme::FSM->connect(
        { namespace => $not_bb },
        alpha => {
            switch => 'bravo_sc'
        }
    );

And, finally, B<A::F> implodes upon itself:

    package Secret::FSM;
    use parent qw/ Acme::FSM /;

    sub connect {
        my $class = shift;
        my $bb = $class->SUPER::connect( @_ );
    } # or just skip constructor, if not needed
    sub bravo_sf {
        shift;
        shift % 42, ''
    }

    package main;

    my $bb = Secret::FSM->connect(
        { namespace => '' },
        alpha => {
            switch => 'bravo_sf'
        }
    );
