Declarative programming is quite elegant, but it is not the same as prompting. I recently had an argument with someone who claimed our declarative code for running analyses over documents was "hard coded". In our product, our approach is to use a functional language approach for analyzing documents. He was an expert in NLP and said that his users required the ability to instruct the system in natural language - English. It still was weird that someone call our declarative program - "hard coded". My, how times have changed.
