/**
 * A plugin that rewrites TypeScript's emitted enums into a tree-shakeable
 * form -- the same as esbuild.
 *
 * For example, consider this TypeScript code:
 * ````ts
 * export enum X { a, b=10, c }
 * ````
 *
 * This is what tsc emits:
 * ````ts
 * export var X;
 * (function (X) {
 *   X[X["a"] = 0] = "a";
 *   X[X["b"] = 10] = "b";
 *   X[X["c"] = 11] = "c";
 * })(X || (X = {}));
 * ````
 *
 * And this is how this plugin transforms the above:
 * ````ts
 * export var X = ((X) => {
 *   X[X["a"] = 0] = "a";
 *   X[X["b"] = 10] = "b";
 *   X[X["c"] = 11] = "c";
 *   return X;
 * })(X || {});
 * ````
