// 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. (function(index) { var o = { [index]: class { constructor() {} // The static method named "name" is added after assigning the // inferred name. static [(index === 0 ? "not-name" : "name")]() {} } } // The inferred name matches the current index. assertEq(displayName(o[index]), String(index)); if (index === 0) { (function self() { self.caller(1); })(); } })(0);
