The lifetimes of the other cells are totally unaffected by the the let,
and nothing in the manual ever suggests that they would be. It doesn't
say they aren't, but it also doesn't say that let doesn't print
anything. Like I said in an earlier post, it's not necessary to list
all the things that an operator doesn't do, since there are an infinite
number of things it doesn't do.
