This reminds me of people who are trying to keep all of the unique
lines in a file, and keep them in order too, who write:
perl -ne 'print if (!$seen{$_}++)' somefile.txt
I occasionally try to point out that this code is in fact incorrect.
Here is one way to make the code correct:
perl -ne 'print if (!defined($seen{$_})); $seen{$_}=1;' somefile.txt
Sure, the first method "looks cooler" but I come from the "it must be
correct" camp.
