isPrime in One Line of Groovy

This line of code is inspired by this post on primality in Perl.

$ groovy -e "println new BigInteger(args[0]).isProbablePrime(99)" 19
$ true          <--- i.e. 19 is prime

I suspect that this will be considered cheating: (a) it evaluates "probable" primes and (b) it isn't in the spirit of the game. But still neat, n'est-ce-pas?

    I think this divides a clever (writes clver code) from an excellent developer (reuses existing code).
