Declaring variables at the beginning of your code is only very slightly better than not declaring them at all.

You should declare them just before you need them and only for the smallest possible block. IMHO of course.

    I do declare variables in the smallest scope possible -- but I do also put them at the beginning of the block. I find it's easier to organize, and I tend to think about my code more before I write it.

      Either you have a lot of very small blocks, or you're contradicting yourself. 

      {
    my $foo;
    ...              # n1 lines
    $foo = bar();
    ...              # n2 lines
    print $foo;
}

      Scope of $foo: n1 + n2 + 3 lines 
      {
    ...              # n1 lines
    my $foo = bar();
    ...              # n2 lines
    print $foo;
}

      Scope of $foo: n2 + 2 lines.

        Erm. I suppose I'm contradicting myself, then.

        I mean to say that I'm not using globals if I can avoid it -- but I do declare variables at the beginning of the subroutines. So the first style you presented is a lot closer to how I write code.
