> {- | This module contains the ast node data types. They are very
>      permissive, in that they allow a lot of invalid SQL to be
>      represented. The type checking process should catch all invalid
>      trees, but doesn't quite manage at the moment. Sorry about all
>      the seemingly pointless type synonyms below, they are an
>      artefact of using UUAGC. You can see labels for the fields by
>      looking at the ag source here:
