I'd be interested in a joke programming language that mimics the modern tone and language used by living royals to order food or ask for trips in their private travel infrastructure and so on.
I tried thinking of a programming language syntax that sounded like Elizabethan English, but I think I only succeeded in making a weirder version of COBOL or ALGOL.
Not exactly what you asked for, but you should look up Chef (not the devops tool). It was part of an MIT Mystery Hunt one year. You could certainly write the recipes with a royal style.
