I had code something like this:
(defn- foo [args] body)
(defmacro bar [args] body)
`(foo ~some-args (fn [~more-args] ~...@body)))
and it complained that foo was not public when I invoked bar from
outside its home namespace.
OK, easy workaround, I thought:
(defmacro bar [args] body)
(let [x foo]
`(~x ~some-args (fn [~more-args] ~...@body)))
And now at the line BEFORE the line that uses the macro:
#<CompilerException java.lang.ExceptionInInitializerError (xxx.clj:182)
>
The cause exception turns out to be:
Caused by: java.lang.ClassNotFoundException: mumble.frotz.foobar
$foo__165

Can anyone tell me what the hell is causing this? How do I work around
it, without making "foo" public?
I have also tried
(defmacro bar [args] body)
(let [x #(foo %1 %2)]
`(~x ~some-args (fn [~more-args] ~...@body)))
with nearly identical results:
Caused by: java.lang.ClassNotFoundException:mumble.frotz.foobar
$bar__169$d_r__171
That is, now it's the #() defined closure that it apparently can't
find.
This is a showstopper. I can't make further progress on this project
until I know how to fix this!
