Hey Internals!
We currently have a couple of things that are broken about constants,
and I wanted to gauge if people are interested in a) fixing it as well

What is "abstract constant"? If you need something that can change, just
use a method. Constant is meant to be a nice way to write something

Other languages allow you to have a contract on fields.
