* A randomly chosen person wins...

* ...unless people actually send in solutions.

* Then the choice is made from the "winning set" of people who submitted
  solutions to the most exercises. (Put differently, if you've submitted
  solutions to strictly fewer exercises than someone else, you're not in the
  winning set.)

* If there's a single contestant in the winning set, that contestant wins.

* Otherwise, the choice of winner is made by me (masak) based as much as
  possible on code quality.

Since "code quality" is a slightly subjective measure, let me give a few
hints of what I'll be looking for:

* Readability.

* Consistency.

* Clarity of intent.

* Algorithmic efficiency.

* Idiomatic use of Perl 6.

* Brevity.

In short, what I'm looking for is top-quality code. That's how you win.

You're free to make use of your own judgment in the shaping of your
code. The only thing I'll have very low tolerance for is plagiarism.
Assume that I'm experienced at reviewing code, and that I'll be able to
spot instances of plagiarism, even non-obvious ones. I won't
disqualify anyone for it, I'll just not consider it a good example
of code quality.

One final thing. Please be aware that, by entering the contest, you're not
guaranteed the prize. That is, I'm not legally bound to hand out the prize
to you for any reasons *you* can think of. I might decide to hand out the
prize to everybody, nobody, or the *worst* coder. I won't, though. I'll
hand out the prize to the best coder. So just be best, and you'll be fine.
