- Subqueries - handle by converting query to "table" with selection as fields? can't think of a typesafe way to handle this.
sub := q.AsTable() q2 := From(subquery).Where(sub.IntField("boop").Eq(2)) - Partial selects - maybe structs are always fully hydrated, partial selects -> maps
- DB adapters - translate queries to eg go-pg queries
- Generate concrete field types
- Fragment escape hatch - support injecting raw sql snippets
- Function expressions
- Cast expressions
- Grouping / Aggregates
