Comment (by patrys):
What if we changed `__repr__` to be safe (only print query params) and
allowed a slice with `Ellipsis` to return a list of first N elements,
possibly executing the query if not evaluated earlier?
Example:
{{{
>>> x = Foo.objects.filter(age__gte=5)
<QuerySet(Foo, …)>
>>> x[...]
[<Foo>, <Foo>, <Foo>, <Foo>, '11 more...']
}}}
