10 Io one liners to impress your friends

It's been ages since I've done anything with the Io language. But after seeing this spate of 10 [language] one liners to impress your friends in Davide Varvello's post I thought I would spend the evening trying it with Io. Here's the gist:

	// 1. Multiply Each Item in a List by 2
	list(1,2,3,4,5) map(v, v*2) println
	// 2. Sum a List of Numbers
	list(1,2,3,4,5) reduce(+) println
	// 3. Verify if a Word Exists in a String
	list("hello", "foo") contains("hello") println
	// 4. Read a File
	File with("foo.txt") readLines println
	// 5. Happy Birthday to You
	for (i, 1, 4, if(i == 3, "Happy Birthday dear Io, " println, "Happy Birthday to You, " println))
	// 6. Filter list of numbers
	list(49, 58, 76, 82, 88, 90) select(v, v > 60) println
	// 7. Fetch and Parse an XML web service
	SGML
	URL with("http://search.twitter.com/search.atom?&q=scala") fetch asXML println
	// 8. Find minimum or maximum in a List
	list(1,2,3,4,5) max println
	list(1,2,3,4,5) min println
	// 9. Parallel Processing
	Thread createThread("Date now println")
	// 10. Sieve of Eratosthenes
	// I've failed to fit the Sieve into one line. But still, 4 lines isn't too bad for a first go.
	Range
	n := 120
	primes := 2 to(n+1) asList
	primes foreach(p, for(i, p, n+1, if(primes contains(p*i), primes remove(p*i))))
	primes println

I'd love to see more. It's a great little activity to get started with a language.
