WPS517: missed cases

[orsinium]

Bug report

What's wrong

"WPS517 | Found pointless starred expression" doesn't report string unpacking, dict constructor, and list conversion:

sum(**dict(a=2))
sum(*'hello')
sum(*list('hello'))

I leave *list() and **dict() for the typed-linter

I am sorry for bumping an old issue, but I really wonder about what this rule. An example in docs does not mak things clear.

Here is a minimalist valid code example

def func(foo, *, bar, **kwargs):
    print(foo)
    print(bar)
    print(kwargs)


request_headers = {"spam": get_spam(), "eggs": calculated_value}

func("value", bar="hello", **request_headers)

Another obvious use case is creating models (I use dummy variables names, but the main point is that I want to show that we must unpack a dict):

calculated_data = {...  # a dict with some dynamic data
foo_bar = PydanticModel(**calculated_data)

I do not understand why I am asked to pass request_headers instead of the **request_headers when I need to pass kwargs from my dictionary with some dynamically generated data.

This is so obvious use case so either I am missing something, or you overlooked such use case when designing this rule. Thanks.
