There are many differences, even with the same Perl version on
different platforms. This also conerncs the IN_PAD flag:
Perl OS MULTI IN_PAD
----------------------------------------------
5.8.7 VMS y -
5.8.6 Linux - y
5.8.6 W2K y y
5.8.0 Digital UNIX y -
5.8.0 Linux - y
5.6.1 Linux - -
5.6.0 AIX y -
I'm a little bit surprised about those may differences, especially
that 5.6.0 != 5.6.0! I would have expected a similar behaviour
in same versions, across all platforms!
BTW: I didn't found Devel::Peek in 5.005 and 5.004. Was there
no support in these versions for the module? Can I download it
from CPAN and install it nevertheless?

Sorry, I can't understand. Docs (perlguts) say, that ADDMULTI is
used to suppress the "used only once" messages. However, as
mentioned yesterday, it is during the compiler pass that events
like this are recognized. So, it makes no sense to attempt to
changes this behaviour at run-time because it's too late at this
time (and as shown yesterday, it simply does not work). Therefore
my question: what's the purpose of GV_ADDMULTI? How run-
time behaviour will change when setting it?

In this case (when using with 'Dump'), there's no difference (except
that the output of the leading RV is omitted).
BTW: are globs always magic? Do you know what their magic
vtbl routines getglob() and setglob() actually do?

Yes, ish - but as you surmised later on I have existing line feeds to cope
with, and a few other wrinkles. But yeah it was effectively that simple to
roll my own.
