+  When the [[Set]] internal method of an Integer-Indexed exotic object O is
+  called with property key P, value V, and ECMAScript language value Receiver,
+  the following steps are taken:
+  1. Assert: IsPropertyKey(P) is true.
+  2. If Type(P) is String, then
+    a. Let numericIndex be ! CanonicalNumericIndexString(P).
+    b. If numericIndex is not undefined, then
