Actually I'm warming to this.

The question of symmetry in == popped into my head later in the day too. In fact it works because str does not know what to do with your object and __eq__ is its own reverse. With obvious definitions, one can demonstrate it in pure Python (on Jython 2.7.0, of course).

>>> sys.platform = Multi('win32', 'java')
>>> sys.platform == 'java'
True
>>> 'java' == sys.platform
True
>>> sys.platform.startswith('win')
True
>>> sys.platform
Multi(set(['win32', 'java']))
>>>

Python: can't help but smile some days.

I guess this magical string should be unhashable, in case it ended up as a key in a dictionary?
