How many places do you see '-d'? How many places do you see '_'? '-d' stands for directory. '_' stands for ??? -d is the same as the unix file test, '_' is the same as ???.

It might be easy for you to remember things like this, bit it isn't for me. I guarantee you, in a week if you showed me -d(_) I'll have to look it up. And who wants to do that?

Where is this code running? Is the performance that important? Is -d $filename so much slower?
