If anyone is curious about this, from the FAQ:

"Assignment to a field of the "unknown" type is rejected because the compiler cannot judge whether the object to be assigned is an acceptable one. Read access to a field of the "unknown" type is permitted, but the field has no specific type and must be refered to through a reference of type Object ."
