I'm not sure if it'll always be correct, but likely yes.

-1: it's a major change and I can't see a good reason to warrant it.
The pain will be much bigger, than the gain [1].

  $ perl -le 'map print, @INC' | grep /lib/

If we touch the first one, we'll screw over everyone who installed
something using  People do that on production, a lot.  We
*might* consider doing a mv in a %trigger*, but that would violate
the "packages do not touch /usr/local" rule.

2nd one... custom-built packages without directory dependencies will
cause trouble, but that's probably not many people.

I'm not sure if trees built with "perl Makefile.PL LIB=~/.lib" would
be affected; if they were -- ouch, that's major.

Easy, no need to change the macros; just a couple of %defines in
perl.spec.  But do not do it without a *really* good reason and
thinking it over.

[1] If we were to push this pain through (forcing everyone to rebuild
    their custom-built perl stuff), it might be worth to consider
    disabling ithreads, to get two gains in one go.  That's about 10%
    performance gain, and I have yet to encounter an application which
    uses these.
    It would be useful to talk to other distributors first, though.
