It's imported this way in astroid because List, Dict, and Tuple are also astroid.nodes so it can become confusing. It's probably worth it to stay consistent accross the code base.

In this file we only use 2 nodes and a lot of different typing stuff. That's why I opted to do it the other way around in this file.
I'm fine with reverting!

Let's keep the old imports (at least for class name that are also astroid nodes).

Reverted to only import typing.

There are some circular import in astroid, between files and between packages, I think importing only what's necessary and not whole package will help to understand what is happening in the code if we want to one day handle the issue.

On the other hand, importing submodules avoid such import errors as we will get notified of those patterns sooner.
But I'll revert if you want me to!

@cdce8p do you have an opinion ? It's been a long time since I tried to fix those circular imports, all I remember is the pain 😄

Let's worry about circular import when they happen or when we fix them, thank you @DanielNoord
