Infinite iterable generator in Ceylon

Question

Is there an easy way in Ceylon to create an infinite iterable which generates each element by calling the same given no-args function? In other words, does the language module offer an equivalent to Java 8's Stream.generate(Supplier<T>)?

Answer 1

Here's what I came up with:

{Value+} generator<Value>(Value() generate) => {generate()}.cycled;

This works because {generate()} is lazy.

Answer 2

No this doesn't actually exist right now and I think the "Ceylonish" way would be something like this:

class Generator<T>(T func()) satisfies Iterable<T> {
    object iter satisfies Iterator<T> {
        next() => func();
    }
    iterator() => iter;
}
