In a lot of ways, yes.
An inside-out class hangs all its attributes off a blessed reference
(of course) just like any other class so you can, for example,
subclass a 'conventional' class as an inside out class. The
conventional class will store its attributes in a hash (or whatever)
and the inside-out class will use the result of calling ident() on
that hash ref as a key into its attribute hashes.
So if you're faced with an existing set of 'conventional' classes you
can certainly use those in the same program as inside-out classes -
and you can subclass those classes as inside out classes.
Is that enough compatibility?
