it would be important that they both get the same object, even ifpriorThinggets assigned over and over so that both functions share the same lexical environment. But as soon as a variable is used by any closure, it ends up in the lexical environment shared by all closures in that scope....
Some packages (e.g.mocha) put their functions (e.g.describe,it) on the global object (poor form!). Since these functions are not defined orrequire'd anywhere in your code,standardwill warn that you're using a variable that is not defined (usually, this rule is really useful for catchi...
