I expect there to be an easy way in Perl to use built-in default idioms, to assert that my input and output are in the UTF-8 character encoding form of Unicode, and to use CPAN modules, all at the same time, and without having to know what an "XS module" is.
Specifically, I want to process many CSV files that I feed to the Perl program via @ARGV. I want to use the CPAN module Text::CSV_XS to parse the CSV records. I don't want to open and close files explicitly; I want Perl to open and close them for me implicitly. I want to continue to use Perl's built-in idioms that permit me to avoid needless extra programming, just as I always have.
