No, it'll be the last thing evaluated or the result of a return()
call. Why haven't you tried this?

Try a simple example:

func = function(){
for(i in 1:10){
  z=list(a=1,b=2)
 }
}

and see what comes back. My suspicion is its not going to be a list of lists.

If you want a list of lists then you'll have to put the list together
yourself from the returns of the .Call, something like (not tested,
but looks okay):

func = function(){
 ret=list()
 for(i in 1:10){
  ret[[i]]=list(i,i*2,i*3)
  }
  return(ret)
}
