A mite of pedantry: the J train (a b c d) is a hook with a fork on the right, and so dyadically acts like a(x, c(b(y), d(y))) Roger himself has dismissed [0]

A mite of pedantry: the J train (a b c d) is a hook with a fork on the right, and so dyadically acts like a(x, c(b(y), d(y))) Roger himself has dismissed [0] hooks as an unfortunate result of J4's myriad train rules, made in the name of tacitable everything, which I lament because for some reason, tacit programming is just so much more satisfying than normally solving the problem.
