? append(1,{})  -- {1,{}} 
? append({},1)  -- {1} 
? prepend(1,{}) -- {{},1} 
? prepend({},1) -- {1} 

No I don't, because the result is identical to when the first argument is a sequence ...

-- Ensuring that the first parameter is a sequence. 
? append({1},{})  -- {1,{}}  
? append({},1)  -- {1}  
? prepend({1},{}) -- {{},1}  
? prepend({},1) -- {1}  
 
-- Performing the 'equivalent' functionality using concatenate 
? {1} & {{}} 
? {} & {1} 
? {{}}& {1} 
? {1} & {} 

Or putting the operation into English text ...

• Create a new sequence such that all the elements in the first argument appear at the beginning of the new sequence, in the same order, and the second argument becomes the last argument in the new sequence.
