The intent here is to agressively prevent people from using struct that is only
meant as a namespace and thus contains only static methods & opCall/opDispatch
etc.

The sample below with fine on Win32 but fails to link on Linux 64-bit:

public struct dummy
{    
    static auto opCall(C)(in C[] name)
    {
        return name;       
    }

    @disable ~this(); //comment this out to avoid error
}

void main()
{
    assert(dummy("ABCDE") == "ABCDE");
}

The error message is:

test_case.o:(.data._D26TypeInfo_S9test_case5dummy6__initZ+0x58): undefined
reference to `_D9test_case5dummy6__dtorMFZv'

That is the destructor symbol is not found - correct it shouldn't been there,
but apparently it's referenced all the same.
