Re^10: a State machine with Roles - possible? (class or instance)

in thread a State machine with Roles - possible?

Sorry, i didn't realize that the documentation was not clear enough (indeed). apply_all_roles() gives a meta to the instance. For example the class of my $door instance is an anonymous class called 'Moose::Meta::Class::__ANON__::SERIAL::16=HASH(0x9ac4b8)'. I have made tests: each door can be in a different state (i'm lazy to share these: while trying to unapply Roles on more complex examples, i have lost these tests)

But i don't manage to unapply a Role, and i think there's a better way anyway (see message below)

    I'd rather say it's wrong. =)

    I checked the code it indeed does, so the POD should better reflect this.

    But thanks it's much clearer now. =)

      Eventually, an example with 2 doors later in this thread. It has 2 doors that can be opened/closed, and locked/unlocked.

      The same could be achieved with only 2 Roles (CanBe::Opened, CanBe::Locked), which would each have a state. But still, i'm happy to have learned how to unapply a Role.
