+// Overview:
+// - The outer function is an IIFE which gets marked as a singleton.
+// - The |o[index]| inner function is then also marked as a singleton.
+// - The |o[index]| inner function has a dynamic name from a computed property name.
+// - The |self| inner function uses |Function.prototype.caller| to reinvoke the outer function.
