Hi, below is an example of DI-dependency injection with 3
versions nested in the code. If you remove the leading //
characters, you will not get the "no property `deliver` for
`service` of type `object.Object`" error. Because version-2I
with interface wants its methods to depend on Object..

The problem is with the deduced type of 'services'. I don't know the
mechanism behind it but the common type of 'truck' and 'ship' are
deduced to be Object. App

Ok, so I'm having a struct that has a constructor that takes a
template parameter. I suppose this question could also be named
`how to initialize constructors with template parameters` but
whatever! The funny thing is, I think that I may have already
found how to do it in the past but I forgot.

No, there is no way to pass template arguments to a constructor

My recommendation is to use a free function or a `static`

Hi,
I'm following this example:
https://dlang.org/spec/cpp_interface.html#using_cpp_classes_from_d
and try to wrap a std::list
base.cpp
```cpp

#include
using namespace std;
class Base
{
public:
virtual void print3i(int a, int b, int c) = 0;
};
class Derived : public B
This is just a guess, but I think the problem is the vtable is incomplete.
Because of this the offsets are wrong. So you wouldn't be calling push_back.
