This is one of the reasons I had suggested making the scope-setting capability an external API, not trying to shim in into a few existing APIs. Your [obj, handler] array is much like calling:
$.hitch.apply(this, [obj, handler]) from my ubertiny hitch plugin: http://higginsforpresident.net/js/static/jq.hitch.js So anywhere you pass a function(){} you can pass a hitched function. All the following syntax examples would work: $("#id").bind('click', $.hitch(myobj, function(){ ... }) ); $("#id").bind('click', $.hitch(myobj, myobj.foo) ); $("#id").bind('click', $.hitch(myobj, "foo") ); While preserving API compatibility for older style calls. It also allows the use of the API outside of events/bind. setTimeout($.hitch(this, function(){ ... }), 1000); And so on. Granted, typing $.hitch() is more than simply passing the params you'd want to hitch natively, but I find it being explicit makes more sense to me and is less magic while still providing a great bit of functionality to the users who grok it.
