grep { s/\d+/a/ } @dd;

This is another instance of a mystery of which I've only recently become aware: The (mis(mis))use of grep in place of the (mis)use of map in place of a for-loop. See this discussion. Just for the satisfaction of my own curiosity, if you or anyone can offer any insight into the rationale behind this strange map/grep usage, I'd be mighty obliged.
