(replying to my own post)

Sorry.  Itchy trigger finger and tired brain.  I didn't read the whole
context of the thread.  Dunno what it's doing here.  Forcing __repr__ to
be called on a print statement?  Funny way to do that.  Like I said, I
don't know, so I'll leave it to someone else to say.

Cheers,
Cliff
