another reason why you should always use warnings

[ #28421 ]
I was trying to figure out why this script not working..


while (<>){
    local $SIG{ALARM} = sub{die "\n"};
    alarm 3;
    print " ",$1 if `bpcoverage -c $_`=~/(VERSION:.*)/;
    alarm 0;
  alarm 0;
  next if $@;

after scratching my head for a while, I decided to add use warnings and strict then I got the complains that $SIG{ALARM} is unregistered signal. ARGH!! how stupid.. should have used $SIG{ALRM}

now I am going to start using strict and warnings no matter the lenght of the script!!
