That's not a type per se, but you can assign wrapper at the
assignment thing.
Like

Is there a way to write a delegate type as being specific for
some parameters and tolerant of anything for others? For example,
I can specify this type:
```d
alias MyDelegateType = void delegate(string name, int age);
```
It would be compatible with a pointer to this function converted

I seem to have found a solution.
Before starting neovim i do a,
dcd-server -I/usr/lib/ldc2/1.29/include/d
Automatic would be better.
I try neovim editor with the language server DCD but it seems no
symbols our found.
Could you guide me to solution ?

According to that C++ / D .object files can interoperate both
ways, but one has to be compiled before the other, order
depending on direction.
My question is, can you have a class C (C++) use a class D
(Dlang) in such a way that D can also use C as i

Use a pointer.

Don't name the module the same thing as the class. Rename it

I think you need to get address of a function:
