I've discovered that the session that fireplace is using doesn't return "out" via my python script.

What abaut with weasel?

Should I try saapas using bang! Or not?

Used Piggieback! With the full line and it works with that session.

I have no idea what vim is sending to nrepl, I wish I had some way of sniffing it.

you could add some strategical echom calls

or some tpope plugin had a debug function

echom nailed it.

There's nothing odd about the setup. :/

Does something I don't understand when evaluating code.

Maybe doing some of the init ops causes out to break.

Or maybe it's the ids, I don't know what they are.

> It is generally the case that request messages should contain a globally-unique :id. Every request must provoke at least one and potentially many response messages, each of which should contain an :id slot echoing that of the provoking request. Seems unrelated, but it might be valuable to look into.
