Hey,
I am not aware of any guidelines regarding the usage of PHP namespaces in MediaWiki and di not find any on MediaWiki.org. Not surprising since 1.20 is the first release in which we can actually use it. So I'm curious on peoples thoughts on how to use this new features, if at all, in core and in extensions. As far as I get it, we cannot simply put it into core without breaking compat all over he place, but could gradually introduce it for new components. For new extensions it's a lot easier of course, which happens to be the use case I'm currently facing, and wondering what to best do. MediaWiki\ExtensionName seems like a reasonable NS for extension classes.
Cheers
