How far does one go? Classes are first-class objects, should we also have
anonymous classes?

>>> foo = (class:
...            def __init__( self, x y ):
...                self.x = x
...                self.y = y
...       )( 5, 6 )
>>>
>>> foo.x
5

I'm a fan of lambda, but when a function is complex enough that it can't be
done in an in-(one-)line lambda then it should be pulled out and given a
name.
