system.time behavior using source

You need to print the result of an expression if used from source().
Autoprinting only occurs at the top level.
E.g.

% cat > systest.R
print(system.time(for(i in 1:100) mad(runif(1000))))
source("systest.R")
user  system elapsed
    0.14    0.00    0.20

If I type the line below at my Rprompt, it works fine. But, if I put the
same line in a file called systest.R and then source that file at
the prompt, nothing happens. IF I use R CMD BATCH, it also works in that
the system.time info is the .Rout file. Is there something I
can do so that this line also works when I source it ?  Thanks. My
information is below.

system.time(for(i in 1:100) mad(runif(1000)))
