extern(C++) and struct (constness mangling problem ?)

[deadalnix]

Hi,

I did face a problem with extern(C++) again. Now we are talkign about 
const member method for structs. Here is a sample code to trigger the 
error :

extern(C++) {
	struct Fail {
		void method() {}
		void method() const {}
	}
}

It will generate the error Error: symbol `_ZN4Fail6methodEv' is already 
defined.

Both method are mangled the same way, regardless of constness.

On a more general basis, interfacing to C++ is damn hard to do safely ! 
If you put asside some mangling bugs, some D choices make it more 
difficult than necessary.

Notably, it's very difficult to map a C++ POD class with a default 
constructor and copy constructor/assignement overload. struct doesn't 
allow for default constructor and copy constructor isn't mappable using 
posblit. final class imply an overhead, and are references types (so 
cannot be passed by value).
