-betterC and extern(C++) classes

[Yuxuan Shui via Digitalmars-d]

I was experimenting with -betterC and found out that C++ classes 
doesn't work. Because the resulting object file needs a symbol 
"_D14TypeInfo_Class6__vtblZ" which is in druntime. I suppose this 
is to support T.classinfo?

Could we remove T.classinfo and make classes work under -betterC? 
Or is there some other reason preventing this from happening?

Thanks.
