File Name: typeof_1.js
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]
