I've seen three common forms used to implement loops with post-conditions: 
  1. do {
    ...
} while($condition)

    [download]
  2. while(1) {
    ...
    last unless $condition;
}

    [download]
  3. LOOP:
    ...
    goto LOOP if $condition;

    [download]
I'm curious what form is the most popular. I understand that perl is about TMTOWTDI so I don't ask which is the form is the best. I merely interested what preferences have Perl monks and why.
