All, Tony Bibbs pointed this out on Twitter, that it appears the code sample in this documentation is incorrect:
http://www.php.net/manual/en/language.namespaces.nested.php Note that the namespaces should be MyProject\Sub\Level but we've got it defined as MyProjectSubLevel in the namespace declaration. Not knowing enough about namespaces, I don't know if this is right or not; if it's wrong I'm happy to file a bug to get it fixed. Brandon
