Before answering in depth, let me confirm, that the next perl will
have a version number on AutoLoader, either 5.57 or higher, so here is
not the problem.

I think, the right answer to the repeating problem that some modules
are only available via upgrading of perl will be the following:

Fragmentize every newest perl into single module distributions and put
them all on CPAN and let the usual CPAN indexing happen on them. E.g.:

As soon as CHIPS uploads perl5.004_05, a process should automatically
produce

  [...]
  CPAN/authors/id/perl/Safe-2.06.tar.gz
  CPAN/authors/id/perl/Text-ParseWords-3.1001.tar.gz
  CPAN/authors/id/perl/VMS-DCLsym-1.01.tar.gz
  [...]

Done right, this will lead to an index on CPAN that doesn't mention
CHIPS/perl5.004_05.tar.gz at all, and instead of what you cite,
CPAN::Shell->r will output

  Package namespace         installed    latest  in CPAN file
  AutoLoader                    undef      5.56  perl/AutoLoader-5.56.tar.gz

and the user will be able to say

  install AutoLoader

and get what he expects. One side effect of this will be that we
finally have a means to get at all perl standard modules as modularly
(sp?) as to the rest of CPAN. It's kind of the opposite of the SDK.
Hmmm. KDS? Kernel Decon Struction?

It's pretty likely that I will try this out during the next days, so
please speak up if anybody sees a problem. (I know, there's still no
solution to Ilya's two Devel::Peek versions)
