Don't think anyone answered this, and Joseph would be the best to 
explain, but IIRC this is true but perhaps misleading.  Perhaps it 
should say returns a new reference to the object.  This was for users 
who wanted to concatenate operations, such as

vector.normalize().resize2D()

as opposed to

vector.normalize()
vector.resize2D()
