I have an object with one attribute that is unserializable (due to it's
containing a Proc).

I am trying to figure out how to do the customized serialization
routines for it.

Assume that my attribute that I don't want to serialize is named
@transient.  If I wanted to make sure that @transient didn't get dumped,
couldn't I just do:

def marshal_dump
  @transient = nil

I'm basically wanting to take advantage of the built-in serialization
but exclude one attribute from it.

Would I have to also create a marshal_load method in this case?

Am I required to come up with a custom marshaling and unmarshaling
scheme for _all_ of the N-1 attributes that I _do_ want to have be
serializable, in order to just exclude this one?
