The plugin fails bundling a module which exports a variable from deconstruction with literal keys.

[!] (commonjs plugin) TypeError: extractors[prop.key.type] is not a function

Example
module.js

const obj = {
    index: 0,
    1: 1,
    2: 2,
    3: 3,
};

let {
    index: a,
    1: b,
    2: c,
    3: d
} = obj;

module.exports = b;

index.js

import b from './module.js';

It seems a rollup-pluginutils failure (here the related issue and PR). Also, the extractNames helper in rollup-plugin-commonjs could have the same issue.
