the proper answer is too long to write (it will be more an article that
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).
