It's been a while since I did any c++ but:
1) I don't see any pointer to pointer polymorphism in there.
2) That c++ code is equivalent to the version of your D code
that works, not the version that doesn't.
I return a pointer from an instance of B and the compiler cast it
implicit to A*. Look what is inside of 'bstore' (instances of B)
and what the type of 'get' is (A*).
And no, the equivalent version would use 'A' as return type of
'get', not 'A*'.
