"\n"; Many years ago when I started doing Perl I picked up the idea that it is always more efficient to do double-quote interpolation than spelling it out with '.' between each element. Of course, that was in the days of Perl4. I assume that is no longer a concern? Was it ever, or was I misinformed? I've done a lot of Perl hacking, but have never spent time digging around in the actual interpreter itself. I also was told that if there are no variables to be interpolated to always use single quotes rather than double quotes, as the extra parsing required was expensive.
