Rails spinoffs - May 2006 - Start/Finish events with $$ function?

Are there available events that can be hooked regarding the $$ function?

For example, my application makes use of a function similar to
$$(''.MyClass'').each(function(element, index) { /* Do something
nifty */ });
and it takes a noticeable amount of time.  I''m thinking that it would
be
beneficial to show a loading image while $$ is processing.  So I was curious
if the $$ function offered any event hooks (beforeStart, afterFinish, etc)
like scriptaculous events do... Does anyone think that this would work?  or
would the browser be locked and not animate the gif?

no, it doesn''t, but you could easily:
Element.show(''loading'');
$$(''.MyClass'').each(function(el, idx) { /* code */ });
Element.hide(''loading'');
