finding if Javascript function has a closure

Question

Is there a way to find if given function reference has a closure and eventually to access to closed variables? I was searching for something similiar to "arguments" property, but in vain.

Edit : outside or inside given function

Are you asking if you can detect a closure at runtime (e.g., by some runtime state query), or if by examining the code, it is possible to spot where closures might be produced? — Ira Baxter

@IraBaxter runtime. Doing code analysis for that seems huge overkill for me — ts.

It may seem like huge overkill, unless you have another solution. — Ira Baxter

Nope, you will never know. That's why closures are used to emulate private members, since you never know what's inside, hence "private".
