Mostly good advice, but I would advise STRONGLY against putting anything in PERL5OPT. It makes your scripts non-portable.

This is plain rubbish. The PERL5OPT environment variable doesn't have anything to do with portability, but with the current (application dependant, personal, temporal) options for perl, which might also be provided on the command line.

If you set up your PERL5OPT, you should know what's in there. If you distribute a suite of perl scripts relying on some value in PERL5OPT, you should inform your audience/customers about its rationale and sensible values. PERL5OPT is an environment variable, same as PERLINC (the latter having a default value). They only have effect if a) perl b) your scripts are already ported/portable.

perl -le'print map{pack c,($-++?1:13)+ord}split//,ESEL'
