sorting out function.bind.bind

Function.bind.bind

1. Function.bind.bind(Function.call) = Function.call.bind
2. Function.call.bind(someOtherFn) = someOtherFn.call
3. someOtherFn.call(newThisValue)

First you set up the 'binder' function.  Note that 'binder' is not an official term, I just made it up:
var bb = Function.bind.bind(Function.call);  // bb ends up as a function: Function.call.bind

then you can use it like so:
var boundfn = bb(someOtherFn); // boundfn is now a function: someOtherFn.call

which is a shortcurt to the equivalent statement:
var boundfn = someOtherFn.call.bind(someOtherFn);

Here is one example of each way of doing it:

var binder = Function.bind.bind(Function.call);
var myfncall2 = binder(myfn);
myfncall2({test: 'this other crap'});

var myfn = function () {console.log("testing: " + this.test)};
var myfncall = myfn.call.bind(myfn);
myfncall({test: 'this crap'});
