Just to add another data point, I didn't find it so. I can code up applescript if I want to completely relying on dynamic documentation. In fact, what surprised me was the ease with which I could pick it up after nearly a decade of touching it. The vocabulary explorer is awesome for scripting applications .. if only applications would care about them. Script editor offers coding up using JavaScript as well as applescript, but I'd any day pick AS over JS for its purpose because mental model is clearly established.
