When I first implemented Emacs Lisp -- before there was an editor to
fit it into -- I was desperately trying to keep it small.
Thus, when implementing error handling, I did not try to represent
error daat in such a way that a handler could analyze the situation
or continue.  So I implemented condition-case and that's all.

handler-bind is a natural step forward, but it might be desirable to make
a way to handle an error and continue from where the error happened.
