| subject | “orderBy” and “removeDuplicates” clauses in “for” comprehensions. | |||
| code |
for (val x <- xs;
val y = 5;
x > y;
orderBy(pred);
removeDuplicates)
yield { x } |
|||
| what happened | Create a list of “x” from “xs”, where x > 5 in an order defined by ”pred” and with all “x” unique. |
|||
| what expected | Adding value definition, “orderBy” and “ removeDuplicates” clauses to “for” comprehensions would make them even more powerfull. It would also simplify writing database queries. | |||

| Added value définition (based on XQuery's let statement), and idea of Fatemeh. |
