Hi!
I have a D template struct that reimplements a C++ class template
with identical memory layout for a set of types that matter to
me. Now, I want to use some C++ functions and classes that use
these template instances, from D. For that, I want to
purposefully alias the D and C++ types. How

I might guess that this is so in general, because such a
library has to successfully work with arbitrary MS VC++ and
that "interop" is defined by MS to work.

That threshold would have to adapt to each system. How about

I am trying to write a client for pretty... well... creatively

the body of the reply (an XML document!). std.net.curl.get()

I've just created a situation in my code that is summarized by

Hi!
How do I wrap an existing C++ class with a virtual destructor in
D? Take, for example, this C++ class:
class Base {
public:
virtual ~Base();
virtual void foo() = 0;
}
What does the equivalent extern(C++) declaration in D look like?
I don't care about calling the destructor. My o
Consider the following code:
```d
class Foo { }
class Bar { Foo foo = new Foo(); }
void main()
{
Bar b1 = new Bar();
Bar b2 = new Bar();
assert(b1.foo != b2.foo);
}
```
The assert fails. This is completely surprising to me. Is this
actually expected?
