Comment:
Django uses backend and field/expression converters. `expression` is a
field or an expression and it's used by backend converters. All converters
have the same signature that's why we keep the `expression` parameter in
`Field.from_db_value()` and `Expression.convert_value()` signatures even
if for them it's the same as `self`.
