I'm interested in using lxml in a project, as underlying parsing layer for BeautifulSoup. The whole project should run on pypy. What's the current status of lxml on pypy? Is it considered production ready?

It's more of an "if it works, it works". PyPy still has several problems that can lead to hard crashes or degraded performance when used with lxml. I haven't looked into them for a while, simply because PyPy isn't of any interest to me. However, if you really want to use PyPy, I can't see any advantages of lxml's parser over plain BeautifulSoup in that setting, so if you want to use BS anyway, just use it for parsing as well. Stefan
