PBP numbers 63-65 Not having PBP, I don't know what 63-65 might be, but I do know that your way violates perlstyle: `open FOO, $foo or die "Can't open $foo: $!";` [download] is better than `die "Can't open $foo: $!" unless open FOO, $foo;` [download] because the second way hides the main point of the statement in a modifier. On the other hand `print "Starting analysis\n" if $verbose;` [download] is better than `$verbose and print "Starting analysis\n";` [download] because the main point isn't whether the user typed `-v` or not.

If you're going to break the rules, might as well break them all . . . . :) My take has always been that using this makes it clear when abnormal termination is the main point (i.e. I expect this condition to be true, so take notice that we can terminate the program at this line). I understand why PBP and perlstyle recommend against it; however as I said I'm partial to it. Take it or leave it as you may.	[reply]
