I don't know the progress of `interface to C++`.
I want to use my C++ functions in `d`.

No singular feature, but the overall cognitive load if you use
the language sporadic. Which could be most users that don't use

Problems classes solve don't usually need copying

Hi everybody!
I understand that D's classes solve some particular problems.
However, they also cause problems because they cannot be copied
when scoped. So how do I get virtual methods on a copyable stack
object?
