+description: >
+  When the base of a property reference is primitive, it is coerced to an
+  object during value assignment
+info: |
+  [...]
+  6. Else if IsPropertyReference(V) is true, then
+     a. If HasPrimitiveBase(V) is true, then
+        i. Assert: In this case, base will never be null or undefined.
+        ii. Set base to ToObject(base).
+     b. Let succeeded be ? base.[[Set]](GetReferencedName(V), W,
+        GetThisValue(V)).
+     c. If succeeded is false and IsStrictReference(V) is true, throw a
+        TypeError exception.
+     d. Return.
