    Create a new generator that uses this generator to produce a value that fulfills the given condition.

    Create a new generator that uses this generator to produce a value that fulfills the given condition. If the condition is not fulfilled, the generator fails (returns None). Also, make sure that the provided test property is side-effect free, eg it should not use external vars.

    Create a generator that calls this generator repeatedly until the given condition is fulfilled.

    Create a generator that calls this generator repeatedly until the given condition is fulfilled. The generated value is then returned. Use this combinator with care, since it may result in infinite loops. Also, make sure that the provided test property is side-effect free, eg it should not use external vars.

    Create a new generator that uses this generator to produce a value that fulfills the given condition.

    Create a new generator that uses this generator to produce a value that fulfills the given condition. If the condition is not fulfilled, the generator fails (returns None). Also, make sure that the provided test property is side-effect free, eg it should not use external vars. This method is identical to [Gen.filter].
