Was I clear enough? Probably not. Let me try to clarify.
I am saying that even if one puts debug code in here :
// $ ( defined as: )
function(selector, context) {
/*
here insert all the debugging, testing and teaching
measures you can think of
*/
// The jQuery object is actually just the init
constructor'enhanced'
return new jQuery.fn.init(selector, context);
}
Even in this limited scope this debug version will be very usefull.
no plugins or anything "awesome".
Also, I preffer to call my jQ development version "SAFE&SLOW". I have
noticed that this title brings the message home much quicker ;o)
