Nice to hear Perl's "die" described as elegant. I think it was maybe
Kent Beck who said he thought it was like committing suicide because you
missed the bus.

Just curious if there is an elegant ruby idiom for opening a file and
getting out with minimal fuss if the file can't be opened. Something
like perl's
open(blah blah) || die "cannot open file"
The obvious seems to be ruby's
begin
f = File.open(blah)
rescue
abort "cannot open file"
end
While that does give me a heck of a lot more fine-grained control over
responding to different error types and so on, it seems a little bulky
and verbose if all I really want is a quick message and a non-zero
exit status.
Am I missing an option or idiom?
Thanks!
