all seem to me work fine with default constructible types. What I need is a type generator which provides a constructor, such that code like this one works for mpl::vectors (or other mpl::sequences) with arbitrary length:
------------- class C { C(std::string const & gaga) {} };
struct gen_linear_hierarchy_with_constructor // your idea missing here { // and here };
typedef gen_linear_hierarchy_with_constructor<mpl::vector<C, C> >::type mytuple;
mytuple mt("test", "Thanks for your help"); ------------------
What you really want is the fusion library (in CVS), which will replace Boost.Tuple: #include <boost/spirit/fusion/sequence/generate.hpp> typedef boost::fusion::result_of_generate<some_type_sequence>::type mytuple; I don't know of another (easy) solution for you.

P.S.: David and Aleksey, if you read this here: I could not find your "coming soon" book at awprofessional.com. What's the current state of the book I wait for so long already ...
