Something like this...
var myAjax = new Ajax.Request( url, {method: 'get', parameters:
parms, onComplete: processRSS.curry(foo)} );
I used to do this all the time in my classes with Function#bind but
since 1.6 they have introduced curry(We cooking rice?) which is a slim
downed version of bind specifically targeted to your use case. enjoy!
As a side note, things may not be as you first expect, the curried
parameter is going to come through first you'll be looking at a
signature more like this...
function processRSS(foo, xmlHttpRequest, responseHeader ) {
Techy demo, gotta look at the source and firebug console to see whats
happenin, http://positionabsolute.net/projects/javascript/CurryTest/
