Remember that Perl was originally architected at a time when memory was at an extreme premium and CPUs were very slow. The internal handling of strings has changed to fit the times but plenty of old source code reflects what used to be.

    How is unnecessary copying saving memory?

    IMHO Perl just reflected the behaviour of C.

      And yet, today's runtime Perl implementations must somehow strive to accommodate all of this "old" source-code, as graciously as it possibly can ... without breaking any of its now-oh-so-old assumptions . . .

    Without some kind of citation or description of what you describe one must assume you're talking through your hat.
