Comment (by mssnlayam):
Is it the case that `filter()` and `exclude()` should produce the
complement of each other? If that is not the case, the obvious queries
would be `WHERE (length = width)` and `WHERE NOT (length = width)`.
If the results should be complimentary, couldn't we use `WHERE (length =
width)` for the filter and `WHERE (length = width)) IS NOT true` for the
exclude. The exclude would be slower, but at least the results would be
consistent.
