DESTRUCT_CLEANUP. o Improved support for mixin. The Pike compiler now supports mixin for symbols that have been declared static. FIXME: Explain in one or two sentences what a mixin is and what it's good for.
FIXME: Should that be protected instead of static?
FIXME: Is this really a change, and why are we talking about mixins
instead of multiple inheritance variables?
o Implicit and explicit create(). The compiler now supports defining classes with both an implicit and an explicit create(). o Warnings for unused private symbols. The compiler now checks that all symbols that have been declared private actually are used.
