Just because a 2 can represent different values doesn’t mean there’s not a system, it just means the system is configurable. This is a good thing, you just have to know how the tool works.

Even if I don’t know what specific values m-2 may hold for a given project, I certainly know a lot more about it right off the bat than whatever .class-name you may have come up with from scratch, and can reference the config to know the rest.
