    77However, in a long-running process (where this bug was found), it can be easily triggered. For example, say I have a "base" queryset with a `Concat()` within an `.annotate()`. I never actually evaluate this queryset, but I use it to construct other querysets which I do evaluate. Because all of these querysets share the same instance of `Query._annotations`, evaluating ANY of these querysets will add an additional level of `COALESCE()` to the SQL generated by the others.
