There's a following example in Vavr documentation:

// 1000 random numbers
for (double random : Stream.gen(Math::random).take(1000)) {
    ...
}

However, I cannot find the above method (gen) on Stream type in vavr javadoc.

These seem to be similar behariors: 

        for (double nonRandom : Stream.range(1, 20)) {
            System.out.println(nonRandom);
        }

        for (double random : Stream.continually(Math::random).take(7)) {
            System.out.println(random);
        }

but is there a Stream.gen() somewhere as well?

Am I searching in the wrong places or is it an out-of-date method mentioned in the vavr user guide?

Yes, vavr documentation is outdated in that regard, as that method got renamed to Stream.continually(...) in pull request 1148 to align with the Scala API.

    Ah, perfect. Thanks for the quick fix. See this for another improvement that could be made to the current usage doc: https://stackoverflow.com/questions/48629111/vavr-property-testing – Simeon Leyzerzon Feb 05 '18 at 22:26
