jQuery.noConflict() changes the value of $ even if $ !== jQuery

Suppose I have the following:

<script src="jquery.js"></script>

<script src="mootools.js"></script>


alert($) alerts mootools' $ function


alert($) alerts 'undefined'


This seems like a bug; it in fact introduces a conflict and breaks mootools. If $!==jQuery, calling jQuery.noConflict() should return without changing the value of $.

I have attached a patch.

Since my line breaks were stripped, here goes again:

<script src="jquery.js"></script> <script src="mootools.js"></script> <script> alert($); /* alerts mootools' $ function */ jQuery.noConflict(); alert($); /* alerts 'undefined' */</script>

Agree with snover. noConflict should be called before loading mootools. Setting the $ to undefined might actually be preferable in other use cases.
