in thread System vs. User module version of List::Util

I just went to the link. I don't see what Perlbrew can do for me. I only have 1 version of perl on my PC. I already install cpan modules without cpan sudo (into my $HOME directory). So what else can it do that isn't obvious?

No matter how hysterical I get, my problems are not time sensitive. So, relax, have a cookie, and a very nice day!

    "...what else..."

    You can easily switch between different versions of Perl to avoid some surprises:

    karls-mac-mini:uagent karl$ perlbrew list 5.14.2threads perl-5.16.2 perl-5.16.3 perl-5.17.7 perl-5.18.0 perl-5.18.1 perl-5.18.2 perl-5.18.2threads perl-5.20.0 perl-5.20.0threads perl-5.22.1-threads * perl-5.24.1threads karls-mac-mini:uagent karl$ perlbrew switch perl-5.18.0 karl-mac-mini:uagent karl$ perlbrew list 5.14.2threads perl-5.16.2 perl-5.16.3 perl-5.17.7 * perl-5.18.0 perl-5.18.1 perl-5.18.2 perl-5.18.2threads perl-5.20.0 perl-5.20.0threads perl-5.22.1-threads perl-5.24.1threads

    You're still messing with the system Perl by overriding which modules get loaded by Perl-based applications. Now, that risk isn't large, because very little actually uses the system Perl. But if you wanted to go the safe route, that would be to install your own Perl. This also have some major benefits: Control over the version of Perl, and the ability to upgrade Perl without breaking anything. As a big-time Perl user, these features should be appealing to you.
