The thing that I noticed was the lack of semantics for creation and
Hence the next missive, "Class Spec" :)
This time I was trying to define just the behaviour of objects that already exist, rather than specifying their creation or how the classes that own the objects behave.
I was going to punt on a lot of the rest for now, but I expect I really shouldn't, so I'lll work up try 2.5 tonight. :)
destruction. Will there be well defined creation semantics, with separate steps for allocation of memory, binding to a class, and initialization of attributes? In what order are these done (inc multiple inheritance issues)? What is the state of the object if an exception is thrown before construction is complete; and how is it cleaned up? Even with GC, we must ask similar questions with respect to object destruction. Will there be finalizers; in what order are they called, and can they throw exceptions?
