What you're saying makes sense to me. Since it's true that casting requires including CPPLanguageRuntime.h in the first place, adding it as a static method to CPPLanguageRuntime itself shouldn't be a problem. I don't think this will be an issue when I try to move CPPLanguageRuntime into the Plugins directory either, so I'm perfectly fine with this solution. I will also see if I can remove CPPLanguageRuntime from the forward declarations, and will try to update this diff tonight or tomorrow.
