Delete a function?

okay, so i understand you can do a “[COLOR=#0066CC]delete[/COLOR] [COLOR=#0066CC]this[/COLOR].[COLOR=#0066CC]onEnterFrame[/COLOR]” kinda thingie in a function if you have attached that function to an onEnterFrame handler, BUT, I can’t find anywhere that let’s me know how i can delete the function all togther, like “delete myFunction();” (which doesn’t appear to work)
is there a way to do this? or is my searching all in vain?
