"lowercase" is a pretty drastic change from CamelCase and camelCase. So far the only argument for it I've seen is, "lldb uses it all over the place." Having one subproject drive the standard for everything else seems backward. It's certainly possible I missed other opinions on this though.

This is not how I described my preference for it. I prefer it generally and find it substantially easier to read code using it.

That said, I think the fact that LLDB uses it does contribute two motivations:

  1. It does show some subset of the community is familiar with it and has found it to be a reasonably good convention for their usage.
  2. It removes some cost of transition.

I wouldn't make the decision because of this, but I also don't think we should ignore these points. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20190222/30ec9365/attachment.html>
