Notes to self

• If one changes a variable, check the whole script for that variable to make sure that the results will be as expected.
• From bart: LA it's often considered good practice to increment the variable in a continue block, to prevent running out of sync when using next.
• Do not print Dumper when trying to display a script in a browser without using <pre> tags.
• Do print Dumper when something goes wrong. The data structure is usually the problem.
• Intrepid: btw, i wish i could explain to a lot of people i know, how efficacious Lady_Aleena's explained strategy can be (to use coding and thinking about coding to master a disquieted state of mind)
• From ambrus: In general, use magic only when normal solutions aren't enough.
• From GrandFather: each time through its loop while asks itself "Can I loop this time? Can I? Can I Can I? Please?" and if the answer is no (false statement) while gets grumpy and stops
• rename will not create directories, be sure to use mkdir in conjunction with rename if the files are also being moved to a new directory.

Things I should get a grip on

• objects
• testing
• SQL
• version control

Silly (and incomplete) code

use strict;
use warnings;

my @courses = qw(salad fish entree oyster dessert);

if (@courses > 3) { 
  my @last = splice(@courses,3,-1);
  my @forks = map { "$_ fork" } @courses;
  my @knives = map { "$_ knife" } reverse @courses;
  my $last = grep { /oyster/ } @last ? 'oyster fork' : '';
  print 'napkin '.join(' ',@forks).' plate '.join(' ',@knives).' spoon
+ '.$last;
}
