Yeah, getting CPPLanguageRuntime out of the general forward declarations does seem a worthy goal. But it would be great to do it in a way that doesn't add so much line noise. I added these methods because it got tiresome to write and read the version you are showing...
Maybe we can add a static:
CPPLanguageRuntime *GetCPPLanguageRuntime(Process &process);
If you are calling LanguageRuntime methods on the CPPLanguageRuntime, you shouldn't need the cast and probably shouldn't be including CPPLanguageRuntime.h. So in that case, you'd just do:
LanguageRuntime *cpp_runtime = process->GetLanguageRuntime(eLanguageTypeCPlusPlus)
which is easy to type and read.
You only need to get a runtime cast as a CPPLanguageRuntime if you are planning to call methods that are in CPPLanguageRuntime.h, so you would be including that header anyway, and then you could use the convenience method from there to improve readability.
