Babel reexports pattern

[guybedford]

The following CommonJS reexports pattern is not currently supported:

      var _styles = require("./styles");
      Object.keys(_styles).forEach(function (key) {
        if (key === "default" || key === "__esModule") return;
        if (Object.prototype.hasOwnProperty.call(_exportNames, key)) return;
        Object.defineProperty(exports, key, {
          enumerable: true,
          get: function get() {
            return _styles[key];
          }
        });
      });

will aim to post a PR and release soon.
