> guessing what is SomeAPIResult

I disagree. It’s not a guess, it is precisely what it is, where the variable name is free to betray me. A sane IDE/linter will tell me if my local assumption is incorrect, where a variable called result_SomeAPIResult relies on an assumed, possibly ancient, state of reality.

You do realize nobody writes code like that, right? Even in static typing land people rely on type inference.

list[SomeAPIResult] in your example is redundant. You can get all the benefits of types without it.

Type inference is good for the writer, not the reader.

Relying on type inference isn’t some rule. Your can find many projects that use it selectively, being explicit where it makes sense. The point of writing code is to make it readable and maintainable. The explicit type isn’t redundant, it’s explicit in presentation, and can be functional, like my example.

I mean, just look at this example. You know the type without having to dig in, do you not? You don’t have to look at the function definition. You know immediately. That’s the point of being explicit, where it makes sense. No guessing, where it makes sense. This is why we have all these type hints now, in a dynamic language: because guessing sucks.
