    >>> class Dumb:
    ...   def __init__(self, val):
    ...     self.val = val
    ...   def __str__(self):
    ...     return "<Dumb val=%s>" % self.val
    >>> d = Dumb(5)
    >>> d
    <__main__.Dumb instance at 0x11042d8>
    >>> print d
    <Dumb val=5>

It's just repr() vs. str(), but the difference can be significant in many
