The plugin suggest using imperative code instead of lambdas

Let's compare the two functions below

void fun1(List<Integers> ints) {
    ints.stream()
        .filter(it -> it > 100)
        .map(it -> it + 10)
        .map(it -> it / 2)
        .forEach(System.out::println)
}

void fun1(List<Integers> ints) {
    for (int i : ints) {
		if (i > 100) {
			int x = i + 10;
			int y = i / 2;
			System.out.println(y);
		}
    }
}

The first function uses a lambda, the second uses an imperative for loop. For the first function, the plugin calculates the complexity of 8 and only 6 for the second one.

If we increase the number of lambdas then the calculated difference of complexity will be even greater. In other words, the plugin suggests using imperative code instead of lambdas.
