I think it's for that reason (i.e. being a Perl 4 thingy) that PERLLIB is tagged as obsolete in many people's heads (including mine) — for example see Motivation behind PERL5LIB and PERLLIB?.

I'm wondering, however, has it ever been officially deprecated for Perl 5? And if so, shouldn't there be a recommendation in perlrun etc. to use PERL5LIB by default these days?
