I've been playing with the Event.observe function as i need it to pass
extra arguments to my callback function and keeping 'this' in the
scope of the callback function Object.
I don't know if theres a better way to do this but thought i would
share it here.
observe: function(){
var args =
> Any thoughts??
I didn't test this, so it's based on assumption – but couldn't you
accomplish the same thing by using callBackFunc.bindAsEventListener
(callBackFunc, extraArg1, extraArg2)? I would imagine that would
retain the proper 'this' reference.

Function#bind already accepts any number of arguments, where first one
is used as a scope object and the rest are plugged directly into a
binded function.
$('myElment').observe('click', callbackFunc.bind(anyObj, extraArg1,
extraArg2));
// => when clicked will invoke: callbackFunc(extraArg1, extr
It doesn't even seem like the original need cares for binding, so how about:
$(element).observe('eventName', func.curry(arg1, arg2...));
?

I've always worked to the convention that if an event is sent to a
function it is the first argument.
So i've created an 'args' function instead that does the same as curry
but returns the reverse :
