Whats in your $PERL5LIB?

Ever wonder whats in your $PERL5LIB? Here is one way to find out:

⚡ echo $PERL5LIB
.:./lib:/home/eric/perl5/perlbrew/perls/perl-5.16.2/lib/perl5:/home/eric/perl5/perlbrew/perls/perl-5.16.2/lib/perl5/i686-linux:/home/eric/perl5/perlbrew/perls/perl-5.16.2/lib/perl5/i686-linux-gnu-thread-multi-64int:/home/eric/perl5/perlbrew/perls/perl-5.16.2/lib/site_perl:/home/eric/perl5/perlbrew/perls/perl-5.16.2/lib/5.16.2

My human eyeballs are not equipped to parse that. Unhelpful. So I put this in my .bashrc:

alias perl5lib='perl -E "say join \"\n\", split \":\", \$ENV{PERL5LIB}"'

Here it is in action:

⚡ perl5lib
. 
./lib
/home/eric/perl5/perlbrew/perls/perl-5.16.2/lib/perl5
/home/eric/perl5/perlbrew/perls/perl-5.16.2/lib/perl5/i686-linux
/home/eric/perl5/perlbrew/perls/perl-5.16.2/lib/perl5/i686-linux-gnu-thread-multi-64int
/home/eric/perl5/perlbrew/perls/perl-5.16.2/lib/site_perl
/home/eric/perl5/perlbrew/perls/perl-5.16.2/lib/5.16.2

Better.
