I agree with the rest of your post, but IMO this would make using classes confusing, C++-style. Structs as value-types and classes as reference-types is one of the hallmarks of D and value types + inheritance just makes everything harder (slicing, etc.), and one of D's advantages is that it's a lot simpler to do what you want without ambiguity. Just my opinion, though.

I esp. agree on stack tracing, though. Debuggers are nice, but not everyone runs their code under a debugger all the time. I tried Tango + Flectioned, which ran great under Linux, but since I develop on/for Windows, this isn't helpful.
