val bi_map : ( 'l1, 'r1 ) t -> left:( 'l1 left -> 'l2 left ) -> right:( 'r1 right -> 'r2 right ) -> ( 'l2, 'r2 ) t

bi_map c ~left ~right maps left over every 'l1 left, and right over every 'r1 right, in c.

val map_left : ( 'l1, 'r ) t -> f:( 'l1 left -> 'l2 left ) -> ( 'l2, 'r ) t

map_left c ~f maps f over the left type of c only.

val map_right : ( 'l, 'r1 ) t -> f:( 'r1 right -> 'r2 right ) -> ( 'l, 'r2 ) t

map_right c ~f maps f over the right type of c only.
