Right Rich, Thanks. But that was a simplified reduction of real usage.
Typically the declare is found in a nested structure:
(describe something
(context fooey
(with bar 42) ; declare comes from this macro
(it works
(should= 42

To put it another way: a top-level do is special-cased to compile and

form, such as list, will be fully compiled, including all contained forms,
and only then executed. In this case, the defn cannot compile because the

briefly, it turns out I was wrong about how Clojure works (that seems to
happen a lot with me). A declare/def defines a var even when it's not
