I suppose most people would agree that well-defined destructor
semantic is a good thing to have. And those who praise try/finally
construct are just trying to say that you can use it to do what you
want, even if in a bit more complicated way.

The main problem, I suppose, is that it *would be* pretty hard to
implement RAII in an efficient and portable way.

Not impossible, of course, but hard.
