The difference between q() and qq() only applies to the characters $, @, \, and the delimiter(s) (parens in this case) and the difference is rather subtle for the last few. Of those characters, I only see \ used and I see it used twice in a row. Now "\\" eq '\\' (they are both a single backslash character) so changing qq() to q() should make no difference at all.
