Re^2: What is code readability?

[wfsp]

My take.

Vertical white space rules!

some_function (
    if_it_wasnt_for,
    bad_luck,
    I_wouldnt_have,
    any_luck_at_all,
) or die "handy place for your error msg\n";

Short names, long names, I don't care. Just make them meaningful. A few moments spent choosing a good name can save hours of misunderstanding (even your own) code later.

Code reuse is a good thing. I like variable name reuse too. :-)
