@SJT What is the recommended way to chain unary functions? Both @ and :: do the job, but I thought the former is recommended.

This is implicit composition ('). You can see this from the parse tree: q)parse "(3#,:)" ' (#;3) ,: In k, the expression ,: corresponds to enlist. This construct is the same as repetition (*) in Python. See: https://code.kx.com/q/ref/compose/

Another excellent paper - thanks Stephen. You mention that iterators iterate through lists and maps. We know that tables are lists, still, it may be worth mentioning explicitly that implicit iteration works on tables as well?
