In an extremely open-minded setup, where any class is prone to change, not only their structure, but also their metaclass, it would seem that a local declaration of the kind (DECLARE (MY-CLASS FOO)) would be totally useless.
Slava Pestov did a few really nice things with Factor. In particular, he had a mechanism that would dynamically trigger recompilation when "open coded/inlined" details changed (e.g. macro redefintion). This declaration would be a good point to store such a hook in CL...

In an ideal world, yes, but ECL must currently stick to an environment (C) which does not allow for dynamic recompilation (no clang embedded yet). I know that SBCL plays some tricks and we have used our own tricks in this sense, but I expected that something more sensible could be agreed upon.
