/**
 * @beta

 *
 * Attaches `Symbol.asyncDispose` methods to the MongoClient, Cursors, sessions and change streams
 * if Symbol.asyncDispose is defined.
 *
 * It's usually not necessary to call this method - the driver attempts to attach these methods
 * itself when its loaded.  However, sometimes the driver may be loaded before `Symbol.asyncDispose`
 * is defined, in which case it is necessary to call this method directly.  This can happen if the
 * application is polyfilling `Symbol.asyncDispose`.
 *
 * Example:
 *
 * ```typescript
 * import { configureExplicitResourceManagement, MongoClient } from 'mongodb/lib/beta';
 *
 * Symbol.asyncDispose ??= Symbol('dispose');
 * load();
 *
 * await using client = new MongoClient(...);
 * ```
