    Matz> Hmm, how about "OldClass = NewClass"?

I'm reminded of a cartoon I've seen.  It pictures a young man working
intently on getting his car door open.  Obviously he has locked
himself out of the car and is attempting to use a long wire though a
crack in the window to work the door open.  It is a tricky and
difficult operation and you can tell by his posture that the problem
has his full attention.  On the other side of the car, the passenger's
door is wide open.

The label on the cartoon reads "Working on a difficult problem".

I feel somewhat like that young man at the moment.
