I wouldn't even care if it was unique to Squeak.  I'm not really sure
how much they get used in Common Lisp... I stayed away from them for a
long time because I just never needed them, and, honestly, the example
in the hyperspec lacks illustration.  The normal HANDLER- macros were
enough.  Christoph's comment and my initial reaction to them are
basically the same.

Right?  Hard to tell what the complexity will look like until after it's
finished.  And the ice cream sundae example... well...  Sure, you'll
learn, but you won't get.

I mean, I'm half done.  What's another half?  ;3
