1.Loki::Factory and Loki::TList

Hi,

I read about the Loki::Factory and Loki::AbstractFactory in the book Modern
C++ Design and couldnt figure out one thing:
If I have several classes, for example the following hierarchie:

clase Base
{
    public:
        Base(Base* pBase) : _pBase(pBase) { }
    protected:
        Base* _pBase;
};

template<typename T, const T myT>
class Derived : public Base
{
    protected:
        T _t;
}

Now I define the following TList:
TYPELIST_3(Derived<int, 1>, Derived<string, "Hello">, Derived<int, 9>)
my_list;

And now I wanna create all the Objects in in the List connected in the chain
of responsibility, that means after the creation I wanna have the following
structure:
Derived<int, 1> --> Derived<string, "Hello"> --> Derived<int, 9> --> NULL
And the factory should return to me a pointer to the beginning so that means
to: Derived<int, 1>.

Ist such a behavior possible with the Loki::AbstractFactory or
Loki::Factory, or do I have to create my own?

Thanks in advance
Sebastian

3.Loki's STATIC_CAST macro

In Chapter 2 of MC++D, Andrei Alexandrescu introduces a macro called
STATIC_CAST. Here is the source related to it:


#ifndef STATIC_CHECK_INC_
#define STATIC_CHECK_INC_

namespace Loki
{

    template<int> struct CompileTimeError;
    template<> struct CompileTimeError<true> {};
}

#define STATIC_CHECK(expr, msg) \
    { Loki::CompileTimeError<((expr) != 0)> ERROR_##msg; (void)ERROR_##msg; } 



#endif // STATIC_CHECK_INC_


I would be grateful if someone could explain to me the reason for the last line
of STATIC_CAST (the cast to void):
        (void)ERROR_##msg;

STATIC_CAST seems to be doing its job even without this line. So why is it
needed?

Cheers,
LRS
