 *
 * @example
 * ```ts
 * import { createPipe } from 'saga-query';
 *
 * const thunk = createPipe();
 * thunk.use(function* (ctx, next) {
 *   console.log('beginning');
 *   yield next();
 *   console.log('end');
 * });
 * thunks.use(thunks.routes());
 *
 * const doit = thunk.create('do-something', function*(ctx, next) {
 *   console.log('middle');
 *   yield next();
 *   console.log('middle end');
 * });
 *
 * // ...
 *
 * store.dispatch(doit());
 * // beginning
 * // middle
 * // middle end
 * // end
