Overview

An object tracking whether a warning has been emitted for a given script tree.

This is shared among all objects in a script tree. Whenever any of those objects encounters a situation in which it wouldn’t produce semantically identical CSS to its input, it calls #warn!. The first time #warn! is called for a given warning object, it prints a deprecation warning.
