I'm not sure what your question is. Generative programming itself is a design process/idiom. I can't really imagine how you'd directly support it with a library, though of course we have lots of tools in Boost that can be used to practice generative programming.

Indeed, my original message missed the mark -- perhaps I'm not sure what my question is either. :-/ Let me try again. I'm wondering about support for the automatic assembly of components as described in [CE2000], based upon defining mandatory and variable (optional and alternative) features of components, plus the creation of domain-specific languages (a la Spirit), but particularly for component configuration. Of course, boost::mpl aides the specific task of static template metaprogramming. Chapters 13 and 14 of the book contain examples of generative programming applied to bank accounts and to matrix computation. It'd be of value if there was an reimplementation of these that used parts of boost as applicable. I think I've more-more-than-less grokked chapter 12 (the list generator). Dave
