Final spec areas. Bugs caught and fixed: - (def name docstring value) used the docstring as the value; now the 3-arg docstring form binds the value and records :doc meta - resolve was a nil stub; now a special form resolving a symbol to its var (nil if unresolved). Added find-ns (non-creating lookup) and ns-name. - in-ns didn't evaluate its arg, so (in-ns 'foo) failed; now evaluates it per Clojure (the integration test's unquoted form updated to the quoted idiom) - #(... %& ...) built %& as a positional param instead of a & rest param; now emits (fn* [... & gen] ...) so %& captures the rest Full public-API spec layer now in place. conformance 218/218, jpm test green.
