Comment(by dd32):

 can you supply some references for why References should be returned for
 PHP4? As far as i'm aware, for simple objects there are no real issues..

 Objects are returned in a lot of locations, for example, WP_Error. There
 are only a few specific locations where references are returned
 (Users/capabilities/Roles) where they are needed due to the object being
 modified by the calling functions. Most other objects in WordPress
 represent something and do not change, as far as i'm aware of, cloning
 such objects shouldnt cause an issue? The local object to the function
 should be cleaned up by the builtin garbage collection when the function
 goes out of scope.
