"I remember once when I typed a piece of code from a
book and I just couldn't get it to compile. I never finished this
book because I spend a lot of time trying to find my mistake and I
gave up on it in the end. A few years later I picked the book up
again, but this time I had a little more experience and I typed the
piece of code in a programming editor. This time I found the
mistake almost immediately. There was a : where a ; should be.
Reading this text you really need to watch closely to see the
difference between ;and: or ,and. when it is in code which is also
new to you it's almost impossible to find. This was something I
overlooked many times and in the editor it showed up immediately,
because it had a different color and the line containing the error
was marked. To save myself some of these frustrating experiences
I'm going to use an IDE this time."
