Exactly. You explicitly invoked a function. println is an odd choice
for the main function - except as an example.
Compare that to:
% echo '(defn my-func [& args] (apply println args))' > test.clj
% java -cp ~/.clojure/clojure.jar clojure.main test.clj
%
Arguably, I invoked "defn", but all that did was compile a function
for me - it didn't run said function. To run it, I need to invoke it
explicitly at the end of the script:
% echo '(my-func *command-line-args*)' >> test.clj
% java -cp ~/.clojure/clojure.jar clojure.main test.clj testing
(testing)
%
I'm thinking the problem - since the command line appears to be
correct, and starts a repl if no script is provided - is that Blah.clj
just defines functions, but doesn't invoke one of them. Without
looking at the script, this is just a WAG, but I recall some
discussion about this issue earlier.
