I would have chosen ?dup<- -- a bit lengthy and awkward to type, perhaps, 
but it's a bit symbolic and more or less follows other established Forth 
conventions.  The ? *prefix* indicates that the word *optionally* does 
something.  In this case, it'd be dup<- , which to me reads as 
'backspace over DUP'.  But, hey, that's just me.  :D
