Ok, this is fun :)

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

Or (cheap way)

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

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;


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

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};

More later if I have time.
