in reply to Embracing functions with parentheses

I'm actually somewhat Python-esque in my use of parentheses. I use as few parens as I can get away with, but I organize my code so that indentation plays the part that parens would for reading purposes.

As for your open/close example, I would write it as so: 

    open my($fh), '>', $filename
        or die "Cannot open '$filename': $!\n";
    print $fh $message;
    close $fh;

    myownfunction($param1, $param2);

I don't pay for my whitespace ... do you? :-)

Being right, does not endow the right to be rude; politeness costs nothing.
Being unknowing, is not the same as being stupid.
Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence.
Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.
