C.caller(); // abc
C.caller = function () { return 'cba'; };
C.caller(); // cab

C.arguments = function () {} ??? // In Chrome && Firefox - TypeError

r225845 fixed JSFunction::put() and JSFunction::defineOwnProperty() to perform ordinary [[Set]] / [[DefineOwnProperty]] for classes and strict functions.
I am adding this test case as part of https://bugs.webkit.org/show_bug.cgi?id=225277.

> C.arguments = function () {} ??? // In Chrome && Firefox - TypeError

This throws TypeError because of https://tc39.es/ecma262/#sec-addrestrictedfunctionproperties.
