You have exactly what you are looking for in the D runtime and
standard library.
Many things changed since the book has been released. I is

Unfortunately, you cant use C++ namespaces. More about
interfacing to C++ here: http://www.dlang.org/cpp_interface.html .
The easiest way to solve this is to write a C function that will
glue your code with the C++ library.
No, it is not a bug.

Peter, having string as immutable(char)[] was perhaps one of the

Perhaps I should think more about it, but right now I am 100% against it, as
it makes the code extremely unreadable to an imperative programmer.

It makes sense to follow that pattern and wrap up everything under

On a second thought... Why would that be a problem? Even if hundreds of

such an overhead? o.O
