My kid's writing a bunch of math in Tex and using it with tools like Desmos and Wolfram Alpha, and Lyx and what not, and then when it comes time to build simulations based on that math... he has to transpile it by hand to a programming language. This is terribly sub-optimal. Sure, one can build a transpiler to do it, but it'd be even neater if the authoring tool was more integrated with TeX math.
