Thanks for the reply, I wasn't familiar with scoped. I was aware
that structs are on the stack and classes are on the heap in D,
but I didn't know it was possible to put a class on the stack.
Might be interesting to see how this is implemented.
After looking up some more C++, I think what I was trying to do
is more like make_unique than unique_ptr.

the proper answer is too long to write (it will be more an

a forum answer ;-), so i'll just give you some directions:
import std.typecons;
{
auto b = scoped!B(); // `auto` is important here!
...
}
`scoped!` allocating class instance *on* *stack*, and
automatically
calls destructor when object goes out of scope.
but you'd better consider using struct for such things, as
struct are
stack-allocated by default (unlike classes, which are reference
type
and should be allocated manually).
there is a big difference between `class` and `struct` in D,
much
bigger that in C++ (where it's only about default protection,
actually).
