There is a syntax disagreement here that's why the D compiler 
is instantly stopping you from doing any symbol generated 
interaction with string in C++ interop. C++ doesn't know 
'string' and C++ mangles with parameters and so passing string 
will make string get involved with the symbol generation and 
since string(std::string) in C++ is a template library, the D 
compiler stops you from engaging with 'string'

I don't think it's related to the existence of std::string at all 
since all dynamic array types are forbidden.

```d
extern (C++) void hello(ubyte[] arg) {
        import std.stdio;
        writeln(arg);
}
```

also fails to compile while this works:

```d
extern (C) void hello(ubyte[] arg) {
        import std.stdio;
        writeln(arg);
}
```
