If you call clojure.tools.namespace.repl/refresh
before requiring any
namespaces referenced in data_readers.clj
, then *data-readers*
gets messed
up somehow. The readers you define in data_readers.clj
won't work even if you
require their namespaces. For example:
$ find -type f
./src/foo/core.clj
./src/data_readers.clj
./src/user.clj
