One of the nice things about open source, and modern development tools, is the ability to easily go beyond the documentation to explore the library code itself.

One of the nice things about open source, and modern development tools, is the ability to easily go beyond the documentation to explore the library code itself. While I wouldn't consider that as a substitute for implementing your own, it is another means of figuring out how a library works and can be seen as more results oriented. Yet it is nowhere near as interesting, in my opinion.
