Pipfile failed to load when trying to lower() tomlkit's Bool object

[felixonmars]

This is what I get when I remove the capture-all except in ProjectFile.read(). Turns out tomlkit parses bool into a Bool object and trying to lower() it fails here. IMHO the if condition should be instance(str), since lower() can only work on that.

cls = <class 'requirementslib.models.pipfile.PipfileLoader'>
source = {'name': 'pypi', 'url': 'https://pypi.org/simple', 'verify_ssl': <tomlkit.items.Bool object at 0x7fec71f19110>}

    @classmethod
    def populate_source(cls, source):
        """Derive missing values of source from the existing fields."""
        # Only URL pararemter is mandatory, let the KeyError be thrown.
        if "name" not in source:
            source["name"] = get_url_name(source["url"])
        if "verify_ssl" not in source:
            source["verify_ssl"] = "https://" in source["url"]
        if not isinstance(source["verify_ssl"], bool):
>           source["verify_ssl"] = source["verify_ssl"].lower() == "true"
E           AttributeError: 'Bool' object has no attribute 'lower'
