Steps to reproduce -

I'm trying to verify if ul tag object exists on the page:
Input:

exists = browser.ul(class_name="foo").exists
print(exists)

Output:

self = #<UList: located: False; {'class_name': 'foo', 'tag_name': 'ul'}>, condition = None, caller = '_elements'

    def _check_condition(self, condition, caller):
        nerodia.logger.debug('<- `Verifying precondition {}#{} for '
                             '{}`'.format(self, condition, caller))
        try:
            if not condition:
>               self.assert_exists()

        if not self._located:
