I don't really agree with this. We have been told before that we would attract more developers to our community if only we allowed backend code to be written in C++ or Rust, and that is not altogether a different thing than saying that we would attract more test developers if only we allowed test code to be written in Python or whatever. The difference is one of degree rather than of kind. We have a lot more backend code than we do test code, I'm fairly sure, and our tests are more self-contained: it's not *as* problematic if some tests are written in one language and others in another as it would be if different parts of the backend used different languages, and it wouldn't be *as* hard if at some point we decided we wanted to convert all remaining code to the new language. So, I have a much harder time imagining that we would start allowing a new language for backend code than that we would start allowing a new language for tests, but I don't think the issues are fundamentally different. But that said, I'm not sure the programming language is the real issue. If I really wanted to participate in an open source project, I'd probably be willing to learn a new programming language to do that. Maybe some people wouldn't, but I had to learn a whole bunch of them in college, and learning one more doesn't sound like the biggest of deals. But, would I feel respected and valued as a participant in that project? Would I have to use weird tools and follow arcane and frustrating processes? If I did, *that* would make me give up. I don't want to say that the choice of programming language doesn't matter at all, but it seems to me that it might matter more because it's a symptom of being unwilling to modernize things rather than for its own sake. -- Robert Haas EDB: http://www.enterprisedb.com
