( my ( $first) = grep /ba/ => @l ) > 1 and warn "not unique\n";

Okay, that is pretty confusing. Wouldn't you expect the outer parentheses to return $first in list context, rather than the number of matches from the grep? After looking at it closely for a couple of minutes, I can see why it works, but it sure doesn't scan quickly.
