i did have reservations when adding the stunt, but i figured the chances
of somebody printing a $reference on purpose, which was not interpolated
in another string already were pretty slim. seems you're the first to
notice in the two years since the "feature" was added :)
btw, just to be clear, $strings passed to $r->print() are not copied, they
are passed by reference, just like any argument to a subroutine. but
most subroutines copy the arguments into their own variables, e.g.:
sub foo {
my ($header, $body, $footer) = @_;
so the idea was that you could pass around references to strings, which
end up being passed to $r->print, without having to worry about
dereferencing.

thanks!
