For fields that are string expressions, the slicing notation should
utilize database functions `Substr`, `Left`, and `Right`. Those functions
could even be deprecated to require the use of slicing notation.
For fields that are iterable expressions, such as `ArrayField`s or
`HStoreField`s, those could utilize slicing notation in a Pythonic manner.
