Its set of features and syntactic elements is incontingent (for example, its templates started as a ripoff of Ada generics which would have been ok except for the completely braindead idea of taking the Ada angle bracket restriction syntax along with it), and it is the task of each programmer to choose a sane and manageable subset and style, and implement using that. As a consequence, every C++ programmer writes his own personal dialect of C++, and we have about 20 different incompatible implementations of multidimensional numeric arrays, making a complete mockery of the "code reuse" mantra: C++ _projects_ can't actually usefully achieve "multiple inheritance" on a design/meta level: once you start with one non-trivial design, fitting other separately evolved components with a different style causes retrofitting nightmares. So going to C++ means cutting down the amount of people who find themselves comfortable with the actual design and layout down to maybe 10% of those who would actually feel ok with the actual _algorithms_ employed. -- David Kastrup, Kriemhildstr. 15, 44793 Bochum - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
