I must confess that I do not understand this sentence. Specifically: as a general rule, adverbs and conjunctions are designed to "add verbs for various domains". This is a core feature of J, and I imagine that the explicit conjunction makes this explicit. Put differently: I think of d. as offering significantly constrained derivation functionality -- far more constrained than what : offers. That said, also, there's a reason that d. is a differentiation mechanism and limits itself to using 0 as the constant of integration when going the other way. And that is to avoid the infinite complexity issues which I think you are alluding to and to focus on some common use cases. And, that said, I do also see a use for more extensive library support for other use cases.
