I forgot to mention in my last email that I'm looking for a champion for
this proposal.

> Hi everyone,
> I've been working on implementing operator overloading and would like to
> submit a proposal.
> I think operator overloading would be a useful addition to the language.
> In particular I think it would be useful for defining operations on common
> mathematical object types such as complex numbers, vectors, matrices, and
> sets.
> I've create a working prototype that consists of:
>    - babel plugin that rewrites operators as function calls
>    - a polyfill which defines these functions and which call the correct
>    argument-specific function based on the arguments' prototypes
>    - Function.defineOperator which can be used to define which function
>    an operator should use for the specified types
>    - "use overloading" directive which allows users to opt-in
> More details can be found at
> https://github.com/kevinbarabash/operator-overloading.
> The babel plugin can be found at
> https://github.com/kevinbarabash/babel-plugin-operator-overloading.
> I also have a demo project at
> https://github.com/kevinbarabash/operator-overloading-demo.
> The design was inspired by some of the slides from
> http://www.slideshare.net/BrendanEich/js-resp.
