class QGroupable expr grouped | expr -> grouped, grouped -> expr

beam-core Database.Beam.Query

Type class for grouping keys. expr is the type of the grouping key after projection. grouped is the type of the grouping key in the aggregate expression (usually something that contains QGenExprs in the QGroupingContext).
