Teachers quite correctly teach that clarity & correctness are more important than performance. It doesn't matter how well something performs if you can't trust the answer it gives. Clarity implies a good design. A good design is more difficult to optimise than a bad design because performance tends to come as a by-product of good, simple, clear design. As MA Jackson put it "The first rule of optimisation is 'don't do it'. The second rule is 'if you have to do it, don't do it yet'". As CAR Hoare put it "There are two ways of constructing a software design; one way is to make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are no obvious deficiencies. The first method is far more difficult." -- Bob -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
