nested higher-order functions

Hi! @sobolevn

What do you think about this code:

res = reduce(
    lambda acc, x: acc + x,
    filter(
        lambda x: x > 5,
        map(
            lambda x: x + 1,
            map(
                lambda x: x * 2,
                filter(lambda x: x % 2 == 0, numbers)
            )
        )
    ),
    0
)

How about adding rules to simplify nesting?

It's should be like this:

step1 = filter(lambda x: x % 2 == 0, numbers)
step2 = map(lambda x: x * 2, step1)
step3 = map(lambda x: x + 1, step2)
step4 = filter(lambda x: x > 5, step3)

please, assign me , if you think it should be a violation :)

No implementation files or tests are identified. Start by reviewing the project's existing rule conventions and decide whether the nested map, filter, and reduce example defines a precise violation; done requires an agreed rule scope and tests covering the proposed behavior.
