Oh I got it. My { reader stops at EOF. So if you are in the terminal rather than in slime, you probably have to issue C-d <return> for the read to ever finish. It seems like no-one could possibly be happy about how that { thing works ;p
Ah yes, it worked from Sly 👍
On an unrelated note, it’d be nice to have some in-built help with the list of commands one can execute. Nice job still, looks promising!
