I used it because it was in NuVoc as well as in the old Vocabulary's Control Structures. (I know very little about using APL and its ins and outs.) I think of myself as an advanced beginner and pretty much stick to about half of the possible primitives, mostly because I have no need of a lot of the higher math primitives. What I continue to learn about the primitives that I know are further applications and nuances of those primitives. After 14 years of programming in J, I don't ever recall encountering a J "meltdown"/crash or a "runaway" program--"knock on wood". (A runaway program, of course, would require an external interrupt of some kind.) Thanks for your comments!
