I agree about the duct tape, which I also use often around the house, so maybe that's why I like org-babel :)

Just wanted to say that I share data between different blocks in different languages through files and env variables (I add :session shared to the src blocks that need to access this). That is useful also to have src blocks you can execute repeatedly and that depend on something like an aws identity being assumed (you just assume it in the first block that shares the session).

I agree it's messy, it's just a mess that works for me.
