I'm not sure how much of it is left today, but there is precedent for Prolog in OS startup:

I wish that logic programming languages (and especially the one used in that article) had more friendly syntax. Even just replacing ":-" with "<-" would be nice...

Actually, Prolog uses "-->" for to define grammars[1] for parsing. Not confusing at all! :)

(actually, parsing is one of the things i really love about Prolog. Writing a simple grammars is much easier and much more pleasurable than using things like regular expressions. The fact that it's far more powerful and readable is just a bonus. )

Are there two layers of caching in that URL?
