I mean you dont need to make a "language" at all, you can just write a librar for all the stuff you need. This stuff is just syntactic sugar.

For example, when I worked on writing embedded software for autopilots, we had 2 files, common.so and common.h that contained essentially a super robust typing framework. The way it worked is that you defined types through the provided functions at the beginning of your code, and all of the definitions were stored and checked at runtime at the beginning before the main execution loop took effect. So basically taking what a more robust language compiler would do and just moving that processing to the start of execution.

I use something similar for my local llm setup at home, where i can have my agent basically write tools for itself and when the tool fails, the error code makes it pretty easy for the agent to fix.
