Kata

Task

You're given a year n (1583 <= n < 10000). You need to create a function which return True if n is a leap year and False otherwise.

Restrictions

Your code mustn't contain:

1. def
2. if
3. eval or exec
4. return
5. import

Note

Feel free to rate the kata when you finish it :)

P.S.: Sofisticated cheats, which do not circumvent the testing framework itself, are welcome.
