Hi all, I think RPython is a very promising language in some scenarios other than implementing PyPy itself. However, the usages (specs) of RPython are not very intuitive. Therefore, after reading the documentations and source code of PyPy/RPython, I started to write a "book" titled RPython by Example. Some chapters are still missing and not complete, and I'll continue improve it. Feel free to ask me any questions about the "book". Thanks.
