+// Overview:
+// - The outer function is an IIFE which gets marked as a singleton.
+// - The |fn| inner function is then also marked as a singleton.
+// - The |self| inner function uses |Function.prototype.caller| to reinvoke the outer function.
+//
+// When we reinvoke outer, we end up cloning a previously reused, i.e. non-cloned,
+// function.
