Perl
Robust scripts
All scripts should start with the following:
use strict; use warnings; use utf8; use autodie;
Only remove one or more of the above if you really know what you are doing.
It is also a good idea to define a minimum Perl version, e.g. to require Perl 5.14 or above:
use v5.14;
More readable names for common variables (e.g. $/
can be referred to as $INPUT_RECORD_SEPARATOR
) can be created with:
use English;
