I start by starting a repl with lein2 in the terminal. This is within a copy of the master branch of https://github.com/lspector/Clojush:



Now launch the emacs app, for which I've installed the latest emacs live distribution as .emacs.d:



I'm not sure what it's sorry about, but in any event I next do M-x nrepl and it asks me for a host:





I replace that with localhost:



Now it asks me for a port, and I replace the default with what the lein2 repl call above gave me:




Now it gives me a repl. Yea:



I know from past experience that it'll give me errors if I try to call functions from my project in this user namespace, so I change into one of my project's namespaces:





That seems to have worked, so I try to call a function in this namespace. The function I want to call is called "print-return" but I just get this far when the screen splits and the cursor leaves the repl and I can't type any more:




Stuck and nothing that I try gets me unstuck. After a while, BTW, without any new interaction from me, it changes to look like this:



What's going on?
