Architecture: Figure out how to get context

Several issues are blocked, because I don’t know yet how to get context.

For example, SIM 201 prevents not a==b and suggests a != b. In general, this seems to be a good rule.

As an exception, I want to leave it like this when it’s in the context of throwing exceptions:

if not (a == b):
    return ValueError("Expected a==b")

But for this I need to know that the boolean operation not (a ==b) is in the context of an if-statement.

Ah, nvm you are using dynamic attrs. Yeah, that will only work if you mark parent as an optional value and subclass them all. 😕
