Comment (by cnassau):
I've attached a patch that fixes the equality test for lazy families.
It leads to testsuite failures in `disjoint_union_enumerated_sets.py`:
these failures are due to pickling problems that were hidden by the
deficiency of the old `__eq__` implementation.
The TestSuite failures would probably be fixed if `_test_pickling` would
check for
{{{
not (f != loads(dumps(f)))
}}}
rather than
{{{
f == loads(dumps(f))
}}}
I'll suggest this in a different ticket.
