<p dir="auto">I know there is an externalHelpers option, but I don't want to add things to my global environment. I want my code to simply import helpers as needed, just like with runtime, but without runtime's other feature of importing things like Map and Set from core-js.</p>
<p dir="auto">As far as I can tell this isn't possible?</p>
<p dir="auto">I'm currently using <strong>babelify</strong> to transform my source code + global shimming <strong>babel-core/browser-polyfill.js</strong> through a vendor file.</p>
<p dir="auto">I noticed redefinitions of _createClass [et al] and the docs mentioned to use <code class="notranslate">{ optional: 'runtime' }</code>, but this has the unfortunate side effect of also including <strong>regenerator/core-js</strong>, extending the dev build time.</p>
<p dir="auto">It would be nice if I can define <code class="notranslate">{ optional: 'runtime.helpers' }</code> and have it include only the helpers.</p>
