22531	Q objects lack a useful repr	Keryn Knight <django@…>	nobody	"{{{

That's not exactly useful, given a Q object may represent a complex tree. As it turns out, Q objects '''do''' implement str, which is the SQL output for the Node subclass, which would be more useful than the above repr, and possibly more useful than the nested repr of .children

The simplest repr implementation would probably be something like:

{{{
def __repr__(self):
    return '{obj.__class__!r} {obj!s}'.format(obj=self)
