Re: Not Using So Many 'if' Statements

[insensate]

Why not:

for(@host){
  $stout = run($_);
  exit unless($stout == 256);
  print "$_ not responding, trying next host\n";
}
print "all hosts not responding";

exit is not really the to be preferred way of leaving a loop, as it completely exits the program and not only the loop.

One should indeed rather use last.

Right... last will break me out of my loop... but why not just exit as soon as I've accomplished the purpose of the script instead of adding an extra command?

Update: Here's what I mean:
Adding the last statement would require an additional conditional:

my $success;
for(@host){
  $stout = run($_);
  unless($stout == 256) {
    $success++;
    last;
  }
  print "$_ not responding, trying next host\n";
}
print "all hosts not responding" unless $success;

Indeed, no reason why you should not use exit to kill the program if you're done. I was just pointing to the side-effects of exit: you may get more more than you bargained for.
