Name Errors/Static/UnsupportedSubscriptArity

Synopsis Wrong number of subscripts is used.

Description Subscription is available for values of various types including: Rascal:String, Rascal:Values/Node, Rascal:List/Subscription, Rascal:Map/Subscription, Rascal:Tuple/Subscription and Rascal:Relation/Subscription. This error is generated when subscription is applied to a value that does support subscription but not the number of indices that are used.

Remedies: correct the number of indices used in the subscription.

Examples

rascal>[1,2,3][2,1];
|stdin:///|(10,1,<1,10>,<1,11>): Unsupported subscript arity of 2 on type list[int]
rascal>("a":1, "b":2, "c":3)["c", "d"];
|stdin:///|(27,3,<1,27>,<1,30>): Unsupported subscript arity of 2 on type map[str, int]
rascal><1, 2, 3>[5,6];
|stdin:///|(12,1,<1,12>,<1,13>): Unsupported subscript arity of 2 on type tuple[int,int,int]
