Should'nt that be orthogonal? Currently, that means persistent class allocated slots are not supported. I never had to use them, though, so I didn't think much about their usefulness... > You might read metaclasses.lisp and classes.lisp if you want a deeper > understanding of how this works. Yes, I only gave them a superficial look before, only to add some locks around slot access (which was surprisingly easy, and though it might not have been very clean, it was working for me...). > You can't call reinitialize instance unless you have an instance to > reinitialize.

Because you're not creating an instance of it, you're creating storage to hold an already created instance of it. > I'm open to a better solution to handling slot initialization in the > fresh vs. reconstituted cases. I'll think on it. It's very pleasant to know a proposal will be welcome. Curiously, Pierre -- [EMAIL PROTECTED] OpenPGP 0xD9D50D8A
