When you asked about discussion and this ran into my mind :)
I remember it was discussed here
http://esdiscuss.org/topic/protocol-library-as-alternative-to-refinements-russell-leggett,
( the syntax in
https://gist.github.com/genericallyloud/7086380 )
Do the semantics proposed above work with what's proposed there?
The "using the function as an extension method" seems pretty similar.
However , Russell's work proposes a form of polymorphic dispatch based on
the extended type. For example:
```js
let dmot = new DoingMyOwnThing("Bob");
dmot::map( n => n * 3;) // calls method `map` of the DoingMyOwnThing
class instead of using the protocol method
```
This is really useful behavior that solves a few very real problems for me
(it's real extension methods) - I think it would be very beneficial for
discussions about bind syntax to allow or at least consider this.
Thanks,
Benjamin
