It's not the most eloquent way to put it, and it's still got some code structure instead simply flowing, but I've never tried this before. It's venting/jest.
#!/usr/bin/perl
use strict;
open (BLACKBOARD, "+>blackboard"); #look around
no strict;
use less 'time';
my $hand = 'reluctant'; @chalk = 'obsolete';
sub cheat {print BLACKBOARD "I will not use Perl in C class\n";}
until ($caught) {
use warnings;
&cheat;
$teacher_enters = int(rand(10));
if ($teacher_enters == 1) {
no warnings;
$caught = "red handed";
close BLACKBOARD;
delete @chalk[1,2,4];
} else {redo}
}
die "You are not to use Perl in C class, start the assignment again!";
