Hi,
sort of new to D programming, coming from C++. Basically the question is if
there is some sort of a way to dynamically cast a variable in D much like you
do in C++?

class C : B {...}
class D : B, A {...}

And arr.ptr returns the pointer to the start of the memory that

I haven't looked into this fully, but for the "the length field and the
