Extensible destructuring proposal

Hello there,

I have written proposal to allow extend standard behavior of object destructuring:

Main idea is, that currently object destructuring is useless for people who use Map or Immutable.Map (https://facebook.github.io/immutable-js/) as their main data structure.

This would allow authors of libraries to create map like structures that would support destructuring. It extends the language in a similar way iterator does.

The main idea is, that if object defines `Symbol.get` method, it gets used to access properties of object instead of `[]` when destructuring.

What do you think?
