Adding a named import

export default function({ types: t }) {
return {
visitor: {
ReferencedIdentifier(path) {
let importName = this.importName;
if (importName) {
importName = t.cloneDeep(importName);
} else {
// require('bluebird').coroutine
importName = this.importName = addNamed(path, 'coroutine', 'bluebird');
}

path.replaceWith(importName);
