If it doesn't work under warnings and strict, there is probably a good reason for that. IMO, if you want to access the loop variable outside the loop, you should declare a separate variable and set it explicitly before you drop out of the loop.
It does work fine under warnings and strict, if you don't declare your variable in the conditions on the for(..) loop. It has always seemed weird to me to write code like 
my $iold;
for my $i ( 1 .. $foo ) {
  if( bar($i) ) {
    $iold = $i;
    last;
  }
}

Doesn't it just seem like a waste of variables? You're clearly using $i and $iold for the same purpose.

As for why it isn't a subroutine, perhaps because I like this code all in one place. Shrug.
