It's worthless. That is to say, there are programs that use it but it doesn't
make sense to have a macro for every possible program that uses unwind-protect,
it's not like it's hard to write it yourself. We have with-open-file
because it's so common and to try and stop naive users from forgetting to
close their files.
Yeah; that is what I thought too. I just wanted to get another opinion
before deciding to leave it out. We must remember to make the documentation
clear enough about how to write your own unwind-protect handler so that
people will do it right. Probably the manual should show the complete
expansion of with-open-file.
