A reminder to those out there, especially HR folks, that the language Perl is always spelled “Perl” and never “PERL.” From the [Perl FAQ](http://faq.perl.org/perlfaq1.html#What_s_the_differenc):
> Before the first edition of *Programming perl*, people commonly referred to the language as “perl”, and its name appeared that way in the title because it referred to the interpreter. In the book, Randal Schwartz capitalised the language’s name to make it stand out better when typeset. This convention was adopted by the community, and the second edition became Programming Perl, using the capitalized version of the name to refer to the language.
> You may or may not choose to follow this usage. For example, parallelism means “awk and perl” and “Python and Perl” look good, while “awk and Perl” and “Python and perl” do not. But never write “PERL”, because perl is not an acronym, apocryphal folklore and post-facto expansions notwithstanding.
Those post-facto expansions are “Practical Expansion and Reporting Language” and “Pathologically Eclectic Rubbish Lister.” Both are bacryonms, created after the language was named.
