I know this point. Maybe that moment, the API is small, the wrapper
core API and features writed in C is not so expensive, but more clear and
But now, the situation has changed, The API became huge, and We need
full feature API in Python, along with the development of bdb.

Yes, the test cases and documents are also very useful when forking a new

Today, there are too much things we need to do, but have ONLY 24 hours :-)
So, we MUST use tools to do what machine can do to improve our productivity.
If not neccessary, I will not write any C code. Because I can not write good
