set binding of methods in an object

[jcblw]

I think it might be cool to be able to pass an object to bound. Then that object's methods would be bound to itself. Its pretty useful to know this will alway be in context of the object in which the method is created I can see it being useful in a situation like this.

function Foo(){
    this.baz = 'qux';
    bound( this ); // binds all methods in the object to the object.
}

Foo.prototype.bar = function(){
  console.log( this.baz );
}

Foo.prototype.qux = function(){
    setTimeout( this.bar, 1000 ); // this.bar will console log 'qux';
}

Perhaps a slight change to the API:

function Foo(){
    this.baz = 'qux';
    bound( this, '__' ); // binds all methods in the object to the object.
}

Foo.prototype.__bar = function(){
  console.log( this.baz );
}

Foo.prototype.qux = function(){
    setTimeout( this.bar, 1000 ); // this.bar will console log 'qux';
}

That is:

bound( <obj>, <prefix> )

would bind all methods on <obj> that start with <prefix> as the method name with the <prefix> stripped.

would this be an requirement or an option?

Maybe we should only take an object to make things clearer:

bound( {
    target: this,
    prefix: '__'
} );

bound( {
    target: this
} );

bound( {
    target: emit,
    events: {
        'foo.bar': 'onBar',
        'foo.baz': 'onBaz'
    },
    obj: this
} );

It's a bit more verbose, but very explicit.
