With the D GC, your object can have three state:
- reachable by GC. If D code can see the reference, then it's
"alive", kept alive by GC scanning. The GC finds the reference
and doesn't touch

That cannot work due to the slicing problem.
C++ cannot have value type classes either for the same reason.
The difference there is that the enforcement is

Returning `i`'s address in a long does not trigger the escape
detector:
It doesn't care about the type of pointer, but

C++ cannot have value type classes either for the same reason. The
difference there is that the enforcement is by guidelines (e.g. "never

I like the distinction between class and struct in D. It
encourages you to think harder about how you intend to use your
types. In C++, there may as well only be one or the other; the

silly me. I should have picked that up myself. thanks.
Ditto for t3. Classes are reference objects, not value objects,
so you must explicitly instantiate

Anyone wanna try converting this C++ example to D?
(I tried, but getting nowhere.. so far).
