Depends. While it is possible to initialise counters in the canonical
"have I seen this before" situation, it's more convenient the way it is at
the moment:

    $seen{$word}++;

looks, to me, nicer than

    $seen{$word} = (exists $seen{$word}) ? 1 : $seen{$word} + 1;

or

    if(defined($seen{$word})) { $seen{$word}++ } else { $seen{$word} = 1 }

or similar.

Cheers,
Philip
