Hi, Tim, Excuse my obstinacy, I still think the problem is in `ob-clojure.el` Because when I: ```org #+BEGIN_SRC clojure :session (ns user-kk) #+END_SRC #+BEGIN_SRC clojure :session :results output (print "hi") (def kkkk "hello") #+END_SRC #+RESULTS: ``` The second block does not return result. when I remove the first block, the second block works. Why `ob-clojure.el` don't evaluate the first block when I press [C-c C-c] on the second block, but still respect the first block's Clojure namespace definition? If it is the way `ob-clojure.el` works. I think this should have an option to disable "respecting babel clojure namespace definition". Because I use "Literate Programming" a lot. I will add some src blcoks with `(ns ...)` as example in Org-mode file.
