C++ uses the process on line [8] above to initialize a class pointer. Obviously it does not work in D. But given the error message at [14], I thought [12] would have been allowed. What is the proper way to convert [8] to D?

Classes in D are already references (like Class& in C++), thus line [8]
would be a pointer to a reference to a class, something which may make
some kind of sense, but is unlikely to be what you want.

Perhaps this question is better answered if you explain why you want a
pointer to a class?
