"""

A simple implementation of the Madey Upy Namey Emulator (MUNE;
https://homebrewery.naturalcrit.com/share/rkmo0t9k4Q ).

Usage examples:

$ python3 -i mune.py
>>> oracle()
('Yes.', None)        # The second element is an intervention, if any.
>>> oracle(bias = 1)  # Advantage
('Yes, and...', None)
>>> oracle(bias = 0)  # Disadvantage
('No, but...', None)
>>> attitude()        # Also accepts a bias.
([2], 'Friendly')
>>> twene()
([8], 'Wild negative')
