You still need to fix the ModelicaCompliance test suite, just edit the [compliance.failures](https://github.com/OpenModelica/OpenModelica/blob/master/.CI/compliance.failures) file and remove the line for `ModelicaCompliance.Connections.Expandable.AugmentArray`.

> @perost, can you please double-check and comment? Yes, `Medium.Liquid.density` and `Medium.Gas.density` both expect a `ThermodynamicState` record that looks like: ```Modelica record ThermodynamicState AbsolutePressure p; Temperature T; end ThermodynamicState; ```...

The model itself is perfectly valid and you can create the equivalent code in OMEdit if you just add classes manually with those names, but pasting it directly into OMEdit...

I did some profiling, and although I aborted it halfway because it would've taken many hours to finish I got some interesting results. One of the main culprits seem to...

#13707 improves the performance a bit, reducing the time on my machine from about 220s to 100s. I found that most of the `List.isMemberOnTrue` calls came from another `List` function,...
