I was trying to turn a terribly lame 4 line piece of code into a one liner and have hit a snag. Consider the code: 
    ($name,$aliases,$addrtype,$length,@addrs) = gethostbyname($machine
+);
    if($#addrs == -1){ next; }
    $ipadrs = join ".", unpack('C4', $addrs[0]);
    @iparray = split(/\./,$ipadrs);

I was able to get it down to this: 
    @addrs = gethostbyname($machine) or next;
    @iparray = unpack('C4', $addrs[4]);

[download]
As close as I have gotten to a one liner is:
    @iparray = unpack ('C4',((gethostbyname($machine))[4]));

[download]
In the above line, if the gethostbyname() function fails because the machine is not available, a warning of uninitialized value is thrown since the array being fed to unpack was never created. I was't able to get it to work using the or next; idea. I'm sure there is a way to do it, I just haven't found it. Possibly a code reference or eval though I don't know much about those. Any tip in the right direction will be greatly appreciated.
