incompatibility with yarn workspaces

**The problem**

While using graphpack in a multi projects setup with yarn, the error below is thrown.

As a workaround, the whole project using graphpack can be moved to yarn's [nohoist](https://yarnpkg.com/blog/2018/02/15/nohoist/).

**The workaround**
package.json:
```json
{
"workspaces": {
"packages": [
"applications/**/*"
],
"nohoist": [
"appname-with-graphpack/**"
]
}
}
```

**The error**
```haskell
