[R] Creating a list of empty lists

Well here is one more brain-teaser related to assigning stuff into a 
list of list. What if I need to create a new list of empty lists? I have 
actually got a solution to this problem:

     l = list(list())
     for ( i in sequence(length-1) )
     {
         l = list(unlist(l,recursive=FALSE), list())
     }

But it is not very neat to do this in a loop. Are there any cuter ways 
to do this?

Best,
Magnus
