I'm not sure how this could work in "other browsers". All methodized
Element methods in prototype.js are late bound - i.e. context is
resolved when the method is called. When you #curry document.observe,
the #observe is not "bound" to document anymore. In the case of -
$ready - it's instead called within a global context and fails.
// first bind the method to its original receiver
// then produce a partial with one argument ('dom:loaded') pre-defined
var $ready = document.observe.bind(document).curry('dom:loaded');
$ready(function(){ ... }); // should work as expected
Another approach is to use "original" Element method - the one that's
context-free:
var $ready = Element.observe.curry(document, 'dom:loaded');
$ready(function(){ ... }); // should work as expected
