This is not to say you can’t do this with other programming languages but it plays to Adas strength of safety, #readability to spot logic errors and the in my eyes unparalleled high-level language support for low-level #bitfiddling for #embedded programming. 😀

You describe what you need with data structures and the compiler sees that the bits end up in the right places.
