    ECMA Section:       11.4.3 typeof operator
    Description:        typeof evaluates unary expressions:
                        undefined   "undefined"
                        null        "object"
                        Boolean     "boolean"
                        Number      "number"
                        String      "string"
                        Object      "object" [native, doesn't implement Call]
                        Object      "function" [native, implements [Call]]
                        Object      implementation dependent
                                    [not sure how to test this]
