Function length

[Irakli Gozalishvili]

Sorry for not being clear about this. Here is a simplified example of the implementation:
https://gist.github.com/2911817  

Also this is just a single particular example, but I expect there to be more. I think what I'm
really asking for is a way to know if …rest is being used.

Also IMO arrow functions should not have `arguments` at all.

Even so, It is hard to imagine a "legitimate" use with dynamically provided functions, particularly as the length values assigned to the existing built-ins don't follow strict rules. At the very least you need to help us understand why your use case is both reasonable and valid.
