Infinite iterable generator in Ceylon

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>)?

Solution

  • Here's what I came up with:

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

    This works because {generate()} is lazy.
