I'm not very firm in Java, but in C++ you can actually read the code on
screen (or as printout!) using Hungarian notation without having to ask
the compiler, what the scope or type of the variable is. Yes, you can
point with your mouse and the editor shows the base type, the class
browser shows you all member variables etc. But having to look for that
again and again, is like reading a book, where you have to ask someone
about the exact meaning of every third word.
And the MS Visual Studio 6 editor isn't very clever too. When you are
using types that are defined based on some base type (e.g. HRESULT,
long), it only shows you the base type. And very often, it doesn't even
recognize the type or class at all. Not very helpful. :-(

That doesn't mean, that I should prefix every variable with package and
class, or does it???
Have fun!
