Kawa also uninterned symbols, as well as CL-style 2-level symbols.
Symbols can be in different packages/namespaces.

(Kawa even has XML-style "qualified names" which can have the property
that two interned symbols are eql? but not eq? because they have the
same local-name,
same namespace-uri, but different symbol-prefix.  It's a bit of a hack
(needed
because of the semantics of XML names), though not directly relevant to
Scheme
standardization.)
