Generators have a * because it is sometimes desirable to be able to create
a generator that does not yield. Consider the following:
function* genIntegers() { var i = 0; while (true) yield i++; }
function* genNothing() { }
function doSomethingWithGenerator(g) { ... }
function foobar(really) { doSomethingWithGenerator(really ? genIntegers() :
genNothing()); }
