It would be useful to have some more detailed descriptions for each pattern. I would put them in the comments above the code. The main questions would be:

• What the pattern is?
• What the current example does?
• Where can the pattern be used practically (or is used in known open-source projects)?

Some of the patterns have comments or are obvious, but not all of them. Also, I think, that people with different computer science knowledge will check them, so it would be valuable to describe the patterns to them.
