Ok, this is fun :)

perl -MFcntl=:flock -e 'print 2+LOCK_EX'

[download]

Or (cheap way)

perl -wle 'print $^W*2**$^W*2'

[download]

Or (Only works if you follow the directions ;-)

#!/usr/bin/perl -w

use strict;

print "Pick an integer between 1 and 3\n";
my $num = <STDIN>;
print "Pick another integer between 1 and 3\n";
$num += <STDIN>;
print "The sum is " . $num;

[download]

Or

perl -wle '%h =  map {(qq{sum}) => $h{'sum'}+=$_ } qw/2 2/; print $h{s
+um}'

[download]

Or (a long version of the above one liner)

#!/usr/bin/perl -w

use strict;

my %foo;
%foo =  map {('sum') => $foo{'sum'}+=$_ } qw/2 2/;
print $foo{sum};

[download]

More later if I have time.

Cheers,
KM
