Error: "Block-scoped declarations (let, const, function, class) not yet supported outside strict mode"

I am getting the following error when adding this module to my project (tried searching around, but can't find anyone else with this problem on this module):

/myproject/node_modules/babel-plugin-react-autoprefix/index.js:10
  let binding
  ^^^

Adding a 'use strict'; to the index.js helps it get a bit further:

/myproject/node_modules/babel-plugin-react-autoprefix/index.js:112
module.exports = ({ types: t }) => ({
                  ^

Seems like it's using modern features, but the runtime is not expecting them. My .babelrc configuration is as follows:

{
  "presets": ["latest", "react", "stage-0"],
  "plugins": [
    "react-autoprefix",
    "react-hot-loader/babel",
    "transform-object-rest-spread",
    "transform-flow-strip-types",
    ["react-intl", {
        "messagesDir": "../build/messages/",
        "enforceDescriptions": true
    }],
  ],
  "retainLines": true
}
