It would be no big deal to create a stack of objects resulting from
the last N expressions. What I'm not too sure about is whether you'd
really want that. Notice that it could imply keeping several copies of
a data set in memory. E.g. the value of an assignment like "data <-
transform(data, logx=log(x))" is the value of the RHS.
