It's not unfortunate, it's normal. Other Lisp dialects have them
both, too. There is a good reason for this: errors can invoke the
debugger.
Emacs Lisp is not Scheme. Does continuation-passing style work
usably in Emacs Lisp now? I don't know for certain, but I would
be very surprised.
If not, let's keep things simple by not trying to define
constructs for that. That simplicity is very important.
