Ah ok, now as soon as I submit it - I see I'm not using this appropriately - but still, it probably shouldn't die like this :-)

nice catch, I'll add some error handling to %d

cosmin commented 12 years ago

Try the latest version. Your comment got me thinking that a naked %d should just describe the last output (*1), so it will now do that by default, as well as handling the cases where the REPL is unable to read or evaluate the form after %d.
