I'm of mixed feelings with vertical alignment of things on separate lines where the lines are indented to the same level. I often won't bother but sometimes do and even (sometimes reluctantly) admit that such can make the code easier to read, though I find that it can clearly be taken too far. For example, lining up punctuation just boggles me even though I've seen code like this:

    my $i               = 1               ;
    my $maxPercentDebit = 100.0+($i/100.0);
    $i               = int                ( $i               );
    $maxPercentDebit = normalizePercentage( $maxPercentDebit );

But I really hate lining up indentation of a line to match the length of code on a previous line. So I'll often rewrite code such as:

    $maxPercentDebit = normalizePercentage( $i,
                                            $maxPercentDebit );

to something more like

    $maxPercentDebit = normalizePercentage(
        $i,
        $maxPercentDebit );

(especially assuming a much longer list of arguments such that it doesn't make sense to group the arguments into a single line).

I even prefer to treat () more like {} and write:

    $maxPercentDebit = normalizePercentage(
        $i,
        $maxPercentDebit,
    );

and in C where the extra trailing comma isn't tollerated, I'd really like to use:

    maxPercentDebit = normalizePercentage(
          i
        , maxPercentDebit
    );

but hold no hope of getting any of my current cow orkers to see the beauty in that. (:
