EDIT: I assume you meant to copy "ìnterops with C++". The answer is that it basically doesn't right now, but they intend for it to in the future somehow.
And if that's a goal, fine, but if there isn't interop yet, we should be hesitant to describe Val as having C++ interop. Especially since C++ interop probably requires some compromises, such as requiring modular C++ in some form.
