Right now they'd do the same as objects, so they'd serialize as an object. Unserializing like that, though... hm, that would probably NOT still be === due to the way PHP handles objects. That's probably undesireable, but I'm not sure at the moment the best way around that. I'll have to discuss with Iliya.

I guess what it comes down to is whether / how easily a class can return an existing instance when asked to unserialize, rather than setting properties on an existing instance. That is, given the string "C:4:Suit:6:{Spades}" can the class definition return the appropriate singleton for Suits::Spades rather than a newly constructed object? If this proves tricky to implement, it would probably be better to forbid serialization than using the default object format and breaking the singleton-ness of the case objects.
