I'm not sure that "notebook" and "reactive" are the two main features I would use to describe Eve, the one language I sort-of know on that list. I think its most distinctive characteristics were that it was synchronous and logic-programming-based (reactive might well imply synchronous, as it indeed did in the '80s and '90s, but I think these days many people think of something else when they hear "reactive" and know little about its original, fundamental aspect -- the so-called synchrony hypothesis).
