Represents a reactive look-up operation, with a computed index (number) or key (string).

Index can be either a number (for IArray lookups) or a string (for IObject lookups).

Diagnostic erros are reported in the following cases:

• If the collection is an IArray and the index is not convertible to a number.
• If the collection is an IArray and the index is not within the bounds of the array.
• If the colleciton is an IObject and the key is not present in the object.
• If the collection is neither an IArray or IObject.
