A google code search for '" -d " lang:perl' produces 108,000 results while a search for '"(_)" lang:perl' produces 6,000.

I'll grant you, some of those -d results are spurious, someone documenting a '-d' command line switch and so on.

Let's try and wrap this up. Do you agree with the statement, "-d $filename" is clearer than "-d (_)"? I'll agree that "-d (_)" is better for performance than "-d $filename". I'll even agree that my first post was stupid. OK?
