After reading through it a lot, I decided to try the J incunabulum code... A digit like 1 or 9 works fine, but if I type 10, it segfaults! Let's see whether I can figure out why that happens just by reading through the code, without taking the lazy shortcut (valgrind)
@vaporeon_ in Latin, it meant “place of origin”, which appears to be its secondary sense in english, and the intended sense here (the J incunabulum being an initial(?) implementation of the language)
@vaporeon_ the apparently purrimary sense in english is fur a book or otherwise piece of textual material dating befur 1501, which i find… oddly specific
@vaporeon_ (and, fur the record, that sense still derives from the latin, but it feels like a stretch of meaning to me)
