Would the resulting code be substantially different from code generated via Clang.jl?

Yeah. The mental model of the Clang.jl approach is also very similar - we would just use Clang.jl to generate an initial Julia wrapper that we can tune manually to...

What's your take on this, @sloede?

Right now, Trixi.jl focuses on first-order hyperbolic systems. Second-order terms still need to be implemented and are on our radar (see, e.g., #704, #356, #497). Thus, we need to focus...

I imagine it could be possible to define some more general interfaces for problem setups. However, creating proper and stable (!) discretizations out of it for general hyperbolic problems is...

That's a bit more difficult since it's part of the algorithm, not a standard keyword argument (since not all algorithms support that).

> `misc_part1` is failing, but it's doing so in other tests too so it should be unrelated to this. Yes, it also fails on `main`...

Thanks for the update, @jlchan! It looks like we all need to think more about it to develop a nice approach.
