By the way please disregard the "-4" part, this is a bug on demangler.com. c++filt works fine and will demangle the symbols properly.

Simplified test-case:

```
extern (C++, `xdr`)
struct xvector(T)
{
}

extern (C++)
public void push_back1 (ref xvector!(xvector!ubyte), ref xvector!ubyte);

extern (C++)
public void push_back2 ()(ref xvector!(xvector!ubyte), ref xvector!ubyte);

void main ()
{
    xvector!(xvector!ubyte) vec;
    xvector!ubyte val;

    vec.push_back1(val);
    vec.push_back2(val);
}
```

Actually, the reduction is a different issue. C++ does not have parameterless templates, so the compiler should probably disallow them since it can't mangle them.
