For the following Python dictionary:

dict = {
    'stackoverflow': True,
    'superuser': False,
    'serverfault': False,
    'meta': True,
}

I want to aggregate the boolean values above into the following boolean expression:

dict['stackoverflow'] and dict['superuser'] and dict['serverfault'] and dict['meta']

The above should return me False. I'm using keys with known names above but I want it to work so that there can be an infinite number of unknown key names.
