Scala - Cyclic Iterators sometimes behave badly - this test will loop forever!

	import org.scalatest.FlatSpec

	class FooSpec extends FlatSpec {

	"foo" should "bar" in {
	val it = Iterator.continually(List[Int]()).flatten
	assert(it.next() == 0)
	}
	}

Ruby's Rational and Complex making me feel uneasy

	Stumbling across Rational and Complex for the first time while working with Date/DateTime,
	found asking myself: Is there some area for work on these in MRI?

	Here is what Ruby Doc says for the Rational class

	Rational(-4) ** Rational(1,2) #=> (1.2246063538223773e-16+2.0i)

	And here is what my local installation of Ruby 2.0.0 says (same for 1.8.7 and 1.9.3, all on OSX 10.7)

	Rational(-4) ** Rational(1,2) #=> (1.2246467991473532e-16+2.0i)

	Hi Donald (and Martin),

	Thanks for pinging me; it's nice to know Typesafe is keeping tabs on this, and I
	appreciate the tone. This is a Yegge-long response, but given that you and
	Martin are the two people best-situated to do anything about this, I'd rather
	err on the side of giving you too much to think about. I realize I'm being very
	critical of something in which you've invested a great deal (both financially
