Polyfilled set objects fails when using inspect

[roy-codefresh]

While using babel-polyfill on IE10 and IE11. The use inspect on a Set object create a fail.

As far is looked, it's seems that isMap function does not distinguish between Set object and Map object.

I was also able to recreate it on node 0.10:

require('babel-polyfill');
var inspect = require('object-inspect');
inspect(new Set([1, 2, 3]));

Does the same thing happen with https://npmjs.com/es6-shim ?

Also, what version of babel-polyfill? core-js fixed a possibly related issue in v2.0

[roy-codefresh]

Answer to your questions:

1. This does not happens on es6-shim.
2. babel-polyfill version is 6.20.0 with core-js@2.4.1

This is a core-js issue - filed as zloirock/core-js#272.

I've added a workaround. v2.5.0+ of core-js won't have this problem, so the workaround won't be needed.
