I'd say prevention is the best cure. Check for duplicates as you read.
You need to prevent duplication raises another question, though. Is an array really
the best data structure for your purpose. The hash structure was created to maintain
uniqueness of keys. Therefore, if you store your elements as hash keys, then you
could be assured that there is no duplication:
if ( defined( $contents{$currentKey} ) ) {contents{$currentKey}++;}
else {$contents{$currentKey} = 1;}
