This should be written

In C++ struct and class differ only in symbol mangling. They
are both value types, support inheritance, copy constructors
etc. By looking at the declaration you can't decide if a class
should be used as value type or reference type, so better treat
it as value type like in C++.
Ah and you're right that this might confuse the user since he has
to know whether the class/struct is POD or not to know whether to
use values or references. Hmm.. also simply adding a virtual
function to a C++ class would break the D code which previously
considered that class POD :)
So maybe you're right, it might be a better idea to make C++
classes values.
