so as Rich mentions in hacker news, you can get declare to work in
other namespaces which does convert the circular dependencies issue
from a compile time problem to a potential run-time one.
The definition is pretty much what you would expect:
(defmacro remote-declare [name]
"declares the supplied ns-qualified name with no bindings, useful
for creating circular dependencies"
(let [[ns v] (.split (str name) "/")
orig-ns (str *ns*)]
`(do (in-ns '~(symbol ns))
(clojure.core/declare ~(symbol v))
(in-ns '~(symbol orig-ns)))))
i'm not really seeing any major downsides to using it. maybe i'm
missing something.
