alt Hacker News> For LLMs, there is an added benefit. If you can formally specify what you want, you can make that specification your entire program. Then have an LLM driven compiler produce a provably correct implementation. This is a novel programming paradigm that has never before been possible; although every "declarative" language is an attempt to approximate it.
That is not novel and every declarative language precisely embodies it.
I think most existing declarative languages still require the programmer to specify too many details to get something usable. For instance, Prolog often requires the use of 'cut' to get reasonable performance for some problems.
