My goal is to build a composable and consistent DSL. It should have few keywords and structures as possible. Of course there's some "fixed keyword" like above crosstab (due to inconsistent SQL syntax i think). "alias" + "fields" helps you build "as (field1, field2,...)" kind of thing. "select" + "from" must form a normal "sql query".
