Correct, I wasn't being serious in said post, sorry for the misunderstanding.
Code:
while(say('Not gonna happen!'));
Will actually print the given text (i.e. "Not gonna happen!") to public chat. Assuming the say() call is always successful, this will essentially result in an infinite loop, even though one would probably get kicked for flooding way before the buffer runs over, crashing and/or freezing the D2 window.
So this will NOT allow you to dupe items, in fact the practical use of this code snipped is fairly little.
