Undocumented reserved names?

[eluser]darrenm[/eluser]
I've just spent a very strange hour or so trying to extend one of my Models with another called "Press".

I was getting "Cannot redeclare" errors which made me think I was loading in files in the wrong order, or extending the wrong objects. But no. In the end I renamed it to "PressRelease" and it then worked fine.

The documentation only contains a very few reserved names and no mention of "Press"

Any ideas? This applies to 1.7.0 out of SVN
