COPY and COPY-IN

[Rem@IMSSS]

Do I understand your proposed semantics correctly, that at the very top
level COPY will force-copy a named object creating an unnamed object with
all the same parts as the original but not EQ to it and inaccessible via
the oblist, but recursively an object is copied if and only if it isn't
named, being a recursion-stop-point if it is named?
(at least that's the proposed default, which could be overriden by
keyword parameters to COPY which become fluid parameters accessed by COPY-IN)
