+/**
+ * The `SubtreeRetainer` class keeps track of a number of pieces of data,
+ * comparing the values of these pieces at every iteration.
+ *
+ * This is useful for preventing redraws to relatively static (or huge)
+ * components whose VDOM only depends on very few values, when none of them
+ * have changed.
+ *
+ * @example
+ * // Check two callbacks for changes on each update
+ * this.subtree = new SubtreeRetainer(
+ *   () => this.attrs.post.freshness,
+ *   () => this.showing
+ * );
+ *
+ * // Add more callbacks to be checked for updates
+ * this.subtree.check(() => this.attrs.user.freshness);
+ *
+ * // In a component's onbeforeupdate() method:
+ * return this.subtree.needsRebuild()
+ *
+ * @see https://mithril.js.org/lifecycle-methods.html#onbeforeupdate
