bad example

Well, the Boost preprocessor metaprogramming library is definitely very useful, but I think your example is imho a bit unfortunately chosen and boost isn't the right thing for this. You'll get bloated code and you have a upper limit of arguments. And it's hard to read. ;)
Why not use the following for this task?

class toStrings
{
	list<string> l;
public:
	template <typename Typ>
	toStrings operator+(Typ obj)
	{
		l.push_back(lexical_cast<string>(obj));
		return *this;
	}
 
	list<string> get(){return l;}
};

usage:
list<string> foo = (toStrings()+"hello"+"world"+42+'h'+123.45f).get();

greetings, iliis
