This is a perfect illustration why normal people (like me, unlike Arthur) have problems working with his apparently brilliant creations, such as the k language. The amount of information required to efficiently read (let alone write) such texts just does not fit into normal people's working memory. One-letter names and the absence of comments don't help either.

(WRT weird names: IIRC, some time ago kdb featured a number of functions named with digits, like '2' being the function to connect to a socket or something.)
