... people who insist that you need to refactor existing, working and less-than-completely-ugly code instead of writing those important missing bits, just because, well, you have to refactor your code after all, don't you? it's just hip and shows how great a programmer you are!

Done properly, supported with unit tests, as part of a disciplined schedule of writing simple, test-driven code, it's only the best way I know of to produce code that can be changed as easily as possible in the future.

    Amen. I always think about it as pre-emptive maintainance.

    Of course, if you only have one day to implement feature X you implement feature X rather than refactor existing code.

    However, the fact that you only have one day indicates larger project scheduling problems - exactly the sort of problems that unit tests, test-driven code and continual refactoring can help with.

    "Done properly" is the key point here. ;) If that's the case, I do agree with you, too, but there are also people who simply rewrite their existing code just for the sake of doing so, transforming it from one state to another one that's different but not really more easily maintainable, easier to understand or showing any other quality that would justify the time they invested in doing it. And there are also bosses with at least somewhat pointy hair that use micromanagement to make *you* do that, even if they are otherwise quite reasonable to deal with. :)

[ovedpo15]: how fast and a good way to print error if more than one out of three variables are defined? for example if there are $a $b $c. I want that if for example $a and $b are defined - print error (also for $a and $c or $b and $c)
[ovedpo15]: its easy with three "if"s or one long "if" but is there a "nice" way :)
