When you are stopped in a frame w/o an obvious typesystem, you are probably going to be running some global routines or looking at global data. If most of system code is C++ having that be the fallback makes sense, but as more system code moves to other languages, maybe this is something we should let users set?

If this is causing issues somewhere right now, we can make a quick fallback to C++ here. I can make a patch later that introduces the option and the according logic to DIL.
