Yes it was in a thread where that was mentioned.  That's not a feature I
would miss, kind of scary (dynamically switching an instance's class).  The
add method stuff though is superb.  It's used to wonderful effect in XML
parsers I've seen for parsing.  If your're curious about the __dynamic__
keyword, here's the thread.  Look in the neighborhood of message #68 and
find the keyword __dynamic__ (wow what a great password this link would
make):
