Sometimes, mistakes stare you in the face and you still miss them. This brief meditation is on the topic of special literals, one of which recently caused a frustrating bug for me. Realizing what had happened was a bracing reminder about when to use the cruciform operator.

For beginning to intermediate monks, ponder the following code snippet:

# In the file 'literal.pl' package Illumination; use strict; use warnings; use Data::Dumper; my %hash; $hash{__PACKAGE__}{__FILE__}{__LINE__} = "Mu Mu"; print Dumper \%hash;

What will it produce? Check your answer.
