breaks webpack: 'return' outside of function

[zaggino]

This package depends on "promise.allsettled": "^1.0.0",

works when forced to 1.0.1, but when resolved to 1.0.2 breaks webpack builds with:

Creating an optimized production build...
Failed to compile.

./node_modules/is-map/index.js
SyntaxError: /usr/app/node_modules/is-map/index.js: 'return' outside of function (12:1)

  10 | \t\treturn false;
  11 | \t};

     | \t^
  13 | }

This seems to be a problem with the promise.allsettled package. It looks like you already opened an issue over there: es-shims/Promise.allSettled#7

Top level return has always been valid in node modules; this seems to be a problem with a webpack configuration.

v2.0.1 of both is-map and is-set have been released.
