My point is trivially true as far as computability goes, but that is not what I ment.

All those abstraction capabilities can be a big detriment to any project, because they always come with a cost, and runtime is far from the only concern.

Specifically in an embedded project, toolchain complications and memory use (both RAM and code) are potentially much bigger concerns than for Desktop applications, and your selection of programmers is more limited as well; might be much more feasible to lock your developers onto acceptable C coding standards than to make e.g. "template metaprogramming" a necessary prerequisite for your codebase and then having to teach your applicants electrical engineering.

Both object oriented programming and compile time computation is doable for a C codebase, just needs more boilerplate and maybe a code-generator step in your build, respectively. But that might well be an advantage, discouraging frivolous use of complexity that you don't actually need, and that introduces hidden costs (understanding, ease of change, compile time) elsewhere.
