Again, the way the language works is baked deep into the project. The stringly-typed nature is everywhere. Using Python isn't going to magically fix that list elements that contain `;` "don't work right". Policy scoping is weird and is not lexical (e.g., policies "stick" to function definitions, so calling a function can cross a policy boundary).

It's one of those "ah, that sounds nice" things that is just too much work once you get down to it (and we have enough compatibility to handle without dealing with the vagaries of umpteen languages as it is).
