    It's like dude went very far out of the way to find some bizarre

    applications?
    I do, in a tokenizer -- I compile a handful of them and then use each of
    them thousands of times. Nobody compiles a million different regexes and
    uses each of them only once.

            And what do you feel are their advantages over Visual Studio?

                Ehm, the main thing about Java is that it tries to keep out feature
                creep. So what I'm missing in C# is any constraint to keep features out.

                It's starting to look as another D language, in which you can do
                anything. That's fine if you are a single programmer that does not care
                about reuse or refactoring, but it's madness for enterprise code.

                That you still have to take care to make things "virtual" is another
                thing I'm really missing.

                In other words: KISS (keep it Simple, stupid) is missing.

                That's not to say that C# does not have a lot of things going for it,
                some features are very useful, like checked code fragments (which, of
                course, should have been the default, just like the virtual keyword).

                    I never met a benchmark I didn't like.

                        I don't think this guy knows what he's doing. There's no possible way "c#"
                        is that much slower. I doubt it's even slower at all. And besides, c#
                        doesn't have a speed. it's only language. It gets compiled to msil. you
                        could time the execution of msil, but not c#. If he was really interested
                        in doing a proper test, he would have at least run a profiler on each peice
                        of code to figure out where the time was spent.

                        Additionally, this nitwit makes the comment that the c# took more lines of
                        code than the java. Not that it really matters, but if it did, it's
                        probably because in the java version he combined several statements on to
                        single lines, where he didn't in c#.
