]> Hi, Nicolas Cannasse seems to believe that "productivity" and "performance" are orthogonal concepts. They are not always. For some tasks the performance of the algorithm determins if the program can be put into the application. Hence, if the program executes too slowly, the program is useless and the time spent on it was a waste. In other words, there was no productivity at all. I commend Nicolas for trying to use O'Caml in a games setting. We, however, can not afford this - instead the company designed and implemented a specific language in order to be able to optimize _and_ be productive. This language has high-level constructs as well as low-level constructs --- and they can be freely mixed. Take care, PKE. --- Nicolas Cannasse <warplayer@free.fr> wrote: > > Some proponents of this mailing list seem to be > > convinced that Ocaml is so much more productive > than > > C++.
