The resolve_expression() method of django.db.models.aggregates.Aggregate
asserts that there is just single source expression. I don't see the
reason for this limitation. There are aggregates (like SQLite's
group_concat) that naturally take in multiple arguments. It seems
group_concat works just fine with multiple source expressions if the
assertion is removed.
